To improve the efficiency of reliable broadcast/multicast MAC protocol in wireless multi-hop network, a location aid algorithm to eliminate redundant nodes was brought forward. Using the neighbor geographical location information, according to the principle of equivalent collision region, the algorithm could reduce redundant nodes from receivers, which is unnecessary for acknowledgement. Thus, the...
To improve the efficiency and flexibility of reliable broadcast/multicast MAC protocol in wireless multi-hop network, a novel adaptive reliable broadcast/multicast MAC protocol (ARBMAC) is brought forward. The core idea of it is based on the broadcast/multicast cost function, which is proposed by analyzing different realizations of reliable broadcast/multicast. According to the function, the most...
Broadcast is a method that allows the nodes in the multi-hop wireless networks share the data efficiently among other nodes. Because the transmissions of broadcast packets are related to send or receive of multi-nodes, it is difficult to ensure the reliable transmission of broadcast packets. In this paper, a new single channel synchronous MAC protocol, termed the three-handshake broadcast protocol...
In wireless sensor networks, the most significant traffic pattern is data gathering from sensor nodes to sink through multihop paths forming a tree structure. This paper presents an energy-efficient MAC protocol based on routing information, EBRI-MAC, designed for such traffic pattern. In EBRI-MAC, an idea of clustering based on data deliveries on the tree is proposed, in which a parent node and its...
