On-demand source routing with reduced packets protocol in mobile ad-hoc networks
A mobile ad-hoc network is a collection of nodes forming a dynamic wireless network without pre-existing infrastructure or centralized administration. Mobile ad-hoc network is mostly used in disaster management, military applications, vehicular communication, etc. Each node in the network acts as a router and uses a routing protocol in order to transfer data in a fully distributed way. In this paper, we focus on the routing problematic in mobile ad-hoc networks and we contribute by proposing DS2R2P (on-demand source routing with reduced packets protocol). Our proposal is based on source routing when the source node embeds the route information in the data packet allowing to drive intermediate nodes in order to reach the intended destination. Unlike existing solutions, the header of data packet includes only a reduced integer value instead of the complete sequence of intermediate node addresses. This value is considered as the summary of the routing path and includes a complete information allowing the data packet to reach the destination. We have evaluated the performances of our solution through simulations in which our protocol provides effective results in terms of data routing delay and communication overhead.
