Wireless sensor actor networks (WSANs) consist of a large amount of sensor nodes with low cost and little actor nodes with better processing capabilities. The actor nodes tend to get partitioned due to low actor density in case of economic considerations. So, the communication among actors requires sensor nodes to relay his data to the destination actor which lead to the bottleneck in communication. A high-throughput disjoint multi-path (HTDM) routing scheme is proposed in this paper which allows actor simultaneously forwards data through multiple disjoint paths to achieve high throughput. HTDM routing scheme can quickly establish multiple disjoint routing paths, which can increase the throughput among actors a lot, and the routing path can be adjusted dynamically according to the energy status of their nodes, which can achieve load balancing. Simulation results show that, compared with related routing schemes, HTDM routing scheme can achieve higher throughput performance and distribute transmission loads more evenly to most of the nodes in the network.
WSANs consist of a large amount of inexpensive sensor nodes and a small amount of expensive powerful mobile actor nodes (e.g. robots) REF .
