Routing Strategy for Avoiding Obstacles During Message Forwarding in Mobile Ad-Hoc Network

It is well known that obstacles like ruins will appear after disaster and it degrades performance of the message forwarding. Hence we propose a scheme to keep communication performance. By the proposal, nodes in the disaster affected area can decide whether there are obstacles around itself, and then change its message routing strategy to successfully forward the message with bypassing the obstacle. According to performance evaluations, we clarify that our scheme has better resistance to obstacles, while keeping higher delivery ratio, low end-to-end latency, and the use of energy, respectively.
