Cost efficient routing in ad hoc mobile wireless networks

Because of the various constraints imposed on ad hoc mobile wireless networks, a cost efficient routing protocol is crucial to the success of an ad hoc mobile wireless network, especially in a dynamic environment such as battlefields. In this paper, we present a cost efficient routing scheme for ad hoc mobile networks by taking advantages of the benefits of traffic aggregation. The central idea of our proposed routing scheme is motivated by the observation that traffic aggregation can reduce the effects of traffic variations. Based on similar studies in the fixed networks, we device a more realistic cost model in ad hoc mobile wireless networks, and propose a routine, scheme based on this cost model that effectively promotes the traffic sharing in ad hoc mobile wireless networks. A much higher traffic variation factor than in fixed networks is used to account for the higher traffic fluctuations in an ad hoc mobile wireless network environment.
