An efficient multipath routing protocol for Wireless Sensor Networks
A Wireless Sensor Network (WSN) is a collection of wireless sensor nodes forming a temporary network without the aid of any established infrastructure. One important issue when designing a WSN is the routing protocol that makes the best use of the severely limited resources presented by WSN. Another important factor is providing as much security to the application as possible. In this thesis, a new routing protocol is proposed called EMR: An Efficient Multipath Routing protocol. EMR alternately uses multipath as the path for communicating between two nodes, thus prolonging the lifespan of the network. On the other hand, EMR is effectively resistive to some specific attacks that have the character of pulling all traffic through the malicious nodes by advertising an attractive route to the destination. The performance of this protocol is compared to the Directed Diffusion protocol. Simulation results show that the proposed protocol surpasses the Directed Diffusion protocol in terms of throughput, control overhead and network lifetime.
