Dynamic Routing for Data Integrity and Delay Differentiated Services in Wireless Sensor Networks
Year: 2016

Applications running on the same Wireless Sensor Network (WSN) platform usually have different Quality of Service (QoS) requirements. Two basic requirements are low delay and high data integrity.These two requirements cannot be satisfied simultaneously. Existing system problems are being resolved using this project. In the previous projects high data integrity with low delay are not done at the same time, using this one we have overcome those issues.  WSNs have two basic QoS requirements: low delay and high data integrity, leading to what are called delay sensitive applications and high integrity applications, respectively. Generally, in a network with light load, both requirements can be readily satisfied. However, a heavily loaded network will suffer congestion, which increases the endto end delay.This work aims to simultaneously improve the fidelity for high integrity applications and decrease the end to end delay for delay sensitive ones, even when the network is congested. We borrow the concept of potential field from the discipline of physics and design a novel potential based routing algorithm, which is called integrity and delay differentiated routing (IDDR) IDDR is able to provide the following two functions: Improve fidelity for high integrity applications. Decrease end to end delay for delay sensitive applications. Literature Survey/ 1. Rapid advances in processor, memory and radio technology have enabled the development of distributed networks sensor nodes can detect and use the wireless media. The basic operation a sensor network is the systematic collection and transmission of data detected for the end user. 2. Wireless body area network (WBAN) has been an active area of research in recent years because of its enormous advantages, particularly related to health systems. The research to develop the quality of service in WBAN is immature due to lack of sufficient to model the behavior of different types of traffic generated from different types of events methodology. It has been clearly shown that the traffic in multimedia sensor nodes used WBANs is having bursty nature and cannot be modeled using Poisson traffic distributions. However, most current available literature related traffic models Multimedia Wireless Sensor Networks (WSNs) is based on the Poisson distribution. 3. For non cooperative networks in which each node is a selfish agent, incentives should be given to the intermediate nodes to let them transmit the data to others. What makes the worst 52 International Journal of Social Sciences Humanities (IJSSH) Volume 2 Issue 3 June 2016, ISSN (Online) 2395 5996 ISSN(Print) 2454 275X case scenario is that in a non cooperative network of multiple jump, endpoints can only observe whether or not the transaction from end to end was successful or not, but not the individual actions of intermediate nodes Therefore, in the absence of properly designed incentive programs, rational and selfish intermediate nodes may choose to forward data packets to low priority or simply discard packets, and could put the blame on the unreliable channel. 4. In an ad hoc network, all communication is via wireless media, usually radio through the air, without the help of corded base stations. Since only direct communication between adjacent nodes distant nodes allowed communicate via multiple hops. Routing quality of service (QoS) in an ad hoc network is difficult due to the network topology can constantly change, and status information available for routing is inherently imprecise. 5. Time wireless communication is essential to allow mobile real time applications, such as communication between mobile robots or communication between vehicles be realized. The real time communication based on events paradigm has been recognized as an appropriate level high communication scheme to connect autonomous components in large distributed control systems. 6. We present a new package delivery mechanism called Routing Protocol Multi Path and multi speed (MMSPEED) for guaranteed QoS probability in wireless sensor networks. QoS provisioning is done in two domains of quality, namely timeliness and reliability. Multiple levels of QoS are provided in the domain of punctuality, ensuring multiple options delivery speed packages. In the domain of reliability, various reliability requirements are compatible with the probabilistic multipath forwarding. These mechanisms QoS provisioning are performed in a localized manner and without information from the global network using the packet forwarding localized geographical increased with dynamic compensation, which compensates for inaccuracies of local decisions as a packet travels to its destination. 7. These aspects create a unique challenge that has not been approached by any MAC before protocol for ad hoc networks. In the MAC layer, a fundamental problem is to know on which nodes need the wireless medium at a given time. Most of existing protocols do The underlying assumption that network traffic is inherently random; however, this assumption does not hold in sensor networks. 8. We present a real time communication protocol for sensor networks, called SPEED. The protocol It provides three types of communication services in real time, ie unicast real time, real time area multicast and Real time zone anycast. SPEED is designed specifically to be a stateless person, with localized overloading minimal control algorithm. End to end communication is achieved in soft real time maintaining a desired rate of delivery by the sensor network through a new combination of feedback control and nondeterministic geographical expedition. 9. Each application has different QoS (quality of service) on the same platform in the wireless sensor network.We are proposing technical coldspots relay algorithm and multipath using technical coldspots. data are improved fidelity and end to end delay sensitivity to overcome problems such as minimizing delay and high data integrity and data fidelity. By applying virtual potential field IDDR hybrid separates packets based on their packages 53  2016, ISSN (Online) 2395 5996 ISSN(Print) 2454 275X weight.and sent to the recipient via different route applications.Data fidelity can be improved by collecting idle buffer space or under flight paths to cache charged excessive packages. 10. Sensor networks are designed to detect and disseminate information on the environment they feel. A criticality detected phenomenon determines its importance to the end user. Therefore the dissemination of data on a network of sensors should be aware of the information.Such information knowledge is essential firstly dissemination of critical information more reliably and secondly to consume resources proportional to the criticality of the information network.
