This paper mainly study on the problem of multi-hop routing path selection in Cooperative Cognitive Radio Network (CCRN). Our objective is to improve the effective throughput of primary users (PUs) while increase the opportunity that secondary users (SUs) can access the licensed spectrum owned by PUs. We combine the multi-hop routing selection problem with the graph-based cooperative game. We propose...
Capacity scaling laws of wireless networks have attracted a lot of attention. In this paper, we study the multicast capacity of bus-assistant VANETs (vehcular ad hoc networks) with two-hop relay scheme, which has not been addressed before. Assume that n ordinary vehicles and nb buses are deployed in a grid-like road framework while the number of roads increase linearly with n. All the ordinary vehicles...
In this paper, we introduce a novel routing algorithm which is based on ant colony system. The objective of this novel algorithm is to solve the problem of energy and congestion control on wireless sensor network routing process. This novel algorithm is able to achieve better load balance and prolong the network lifetime. In this novel algorithm we combine the pheromone released by multi-ant colonies...
