How to get a better balance between the push and pull of the event data is the common goal of the various data dissemination algorithms in wireless sensor networks (WSNs). And the characteristics of the any-type query in WSNs is different from the All-type query. At this basis , the load of the system hotspot should be further decreased and the number of(More)
Influencing by the design principles of traditional layered protocol stack, current MAC protocol designing for wireless sensor networks (WSN) seldom takes load balance into consideration, which greatly restricts WSN lifetime. In this paper, FE-MAC, as a novel forwarding election-based MAC protocol, is presented to prolong WSN lifetime by means of improving(More)
Influenced by the design principles of the layered network protocol stack, current MAC protocols in wireless sensor network usually resort to improving energy efficiency as a major energy saving means, with little considerations of load balance, which limits the network lifetime. In this paper, a forwarding election-based MAC protocol, FE-MAC, is proposed.(More)
The geographic routing technology is good for the self-organizing and large-scale Wireless Sensor Networks(WSNs), and the energy-limited sensor nodes require the energy used for routing to be minimum. In this paper a new energy-efficient geographic routing algorithm is proposed and it is distributed and based on the geographic routing, the topology(More)
