An Interference Avoidance Routing Protocol for Wireless Networks

In wireless networks, interference between nodes is an important factor which affects the performance of communications. In this paper, we propose an interference avoidance routing protocol (IARP) that chooses a route with fewer collisions and show that the new routing algorithm is stable. The idea is to collect the busyness information about nodes, and use this to determine the next hop based on the backpressure routing algorithm. From the simulation results, we observe that IARP can achieve better performance in terms of network delay than the pure backpressure routing protocol.
