Energy efficient multicast routing is one of the fundamental problems in wireless sensor networks (WSNs). Previous work has shown that when the goal is to find multicast trees with minimum transmission cost, the problem becomes NP-complete. In this work, we present a heuristic distributed minimum transmission multicast routing protocol (MTMRP) for WSNs. By introducing the biased backoff scheme and...
With the constant development of multimedia technologies and mobile devices, the demand of transmitting multimedia streams to mobile devices will be one of the major applications in wireless networks. But the categories of devices and user preference vary widely. How to provide appropriate multimedia streams to mobile terminals and how to process the received multimedia content in the user side will...
In this paper, we design a destination-driven on-demand multicast routing protocol for wireless ad hoc networks. The design objective is to improve the multicast forwarding efficiency. To achieve this goal, the path to reach a multicast destination is biased towards those paths passing through another multicast destination. If multiple such choices are available, the one leading to the least extra...
With the increasing demand for realtime multicast service in mobile wireless sensor networks (mWSN), it is needed to provide new rendezvous point (RP) selection schemes for mWSN. Due to the arbitrary node mobility in mWSN, where mobile nodes usually go beyond someone RPpsilas coverage, multicast algorithm requires not only end-to-end constrained latency, but also short RP-switch time and low routing...
In mobile sensor networks, the mobility of nodes leads to frequent changes of network topology, therefore the communication links between source nodes and sink vary dynamically. The receiver based routing protocols do not need to establish global routing between source nodes and sink, but allow the neighbor nodes of the sender to contend for the forwarding right under certain rules, and only the contention...
