A Mobility-Aware Channel Allocation Strategy for Clustered Ad hoc Network

This paper presents a mobility-aware channel allocation strategy for clustered ad hoc network. Our main novelty is to consider the mobility associated with the number of times that the channel with larger spectral distance is allocated to guide the channel allocation process, while quickly responding to changes in the network topology. In our performance evaluation, we use a realistic mobility model based on user behavior and we consider the evaluation metrics of throughput, packet delivery rate, end-to-end delay, overhead, and spectral distance. Obtained results show that our strategy presents lower overhead when compared with TABU algorithm, higher throughput, and lower end-to-end delay when compared with RANDOM and LD algorithms.
