Broadcasting is a common operation in ad hoc routing protocols to resolve many issues. However, blind broadcasting is usually very costly and will result to serious redundancy, collision and contention. In this paper we propose a conditioned forwarding algorithm for broadcasting of on-demand multicast routing protocol. By reducing unnecessary broadcasting of route request packets based on additional...
Broadcasting is a common operation in on-demand multicast routing protocol to establish and refresh routing table. A straightforward broadcasting by flooding is usually very costly and will result in serious redundancy and contention. A conditioned broadcasting algorithm for on-demand multicast routing protocol is proposed, which computes the rebroadcast probability of packets through neighbor node...
The Application level multicast is an important technique for indirect communication model. However, there are few works to integrate them together. An Infrastructure for Application Level Multicast Routing in Publish/Subscribe system (IALMRS) is proposed in this paper. We realize a multicast routing protocol for such Publish/Subscribe systems based on IALMRS. From the tests for this multicast routing...
The energy conservation is the intrinsic issue of the wireless sensor network (WSN). The lack of energy of some necessary sensor nodes will affect the accurate data aggregation as well as the effective lifetime of the network. In this paper, the problem of predicting which energy level the WSNs or nodes stay in is addressed. Since the primitive method that exchanges messages through nodes could not...
