摘要

It is quite common that the existing communication facilities are damaged or destroyed in a disaster. Wireless ad-hoc network is a distributed wireless network system which does not rely on any fixed infrastructures and is capable of self-adaption to the dramatic network changes and thus has been wildly used in emergency communications. Recently, many researchers have tried to introduce NDN [1] techniques into such context, showing unparallel advantages in terms of throughput, delay, reliability,etc. This paper focuses on a particularly interesting issue in an NDN based wireless ad-hoc network, that is how to maximize the lifecycle of an NDN emergency communication network given limited power at each node. We proved, in many scenarios, that the unbalanced energy consumption in an NDN based wireless ad-hoc network generally is more serious than that of in an IP-based one, due to the existence of cache. Thereafter, we proposed a novel energy-saving caching and forwarding scheme to achieve better energy load balancing using CS popularity increment table(CPIT) as its indicator. Our simulation experiment with ndnSIM2.0 [3] on a topology generated by BRITE indicates that the proposed scheme can significantly extend the life span of a network by 32% or 58% in contrast to the native NDN scheme, respectively, under two different application scenarios.
