Abstract
How to efficiently build routes among nodes is increasing important for mobile ad hoc networks (MANETs). This paper puts forward an interference aware routing protocol called Interference aware cross layer routing protocol (IA-CLR) for MANETs based on the IEEE 802.11 medium access layer (MAC). By defining the node's sending and receiving capabilities, IA-CLR can indicate the interference strength of the link in a real and comprehensive way. Further more, in order to choose the route with minimum bottleneck link interference, a new routing metric is proposed by combining the MAC layer and the network layer for cross layer design. Simulation results show that IA-CLR can significantly improve the performances of network such as the average end-to-end delay, the packets loss ratio and the throughput.
