In this paper, an energy-efficient cooperative geographic routing (ECGR) is proposed for Wireless Sensor Networks(WSN). ECGR fully takes advantage of cooperative diversity and "multi-sensor diversity" to reach energy-efficient routing. At physical layer, thanks to the high redundancy of the nodes in WSN, the nodes that have correctly decoded the packet are selected to realize "multi-sensor...
In wireless sensor networks with mobile sinks, it is a challenge to design reasonable data dissemination protocols to realize reliable, real-time and efficient data transmission from multiple sources to multiple sinks. Recently, many protocols such as TTDD, GHT and LBDD are proposed to solve this problem. However, most of them depend on the whole network topology information to optimize the data dissemination...
