Sensors in sensor networks are operated by their embedded batteries and they can not work any more if the batteries run out. The data collected by sensors should be transferred to a sink node through the efficient routes. Many energy efficient routing algorithms were proposed. However, the previous algorithms consume more energy since they did not consider the transmission range and direction. In...
In wireless sensor networks, most of the existing key management schemes, establish shared keys for all pairs of neighbor sensors without considering the communication between these nodes. This results in causing huge overhead. For large scale WSNs, these schemes still need each sensor to be loaded with a bulky amount of keys. In many-to-one traffic pattern of sensor networks, large numbers of sensor...
Constant growth in the wireless sensor network (WSN) needs routing protocol which can cater for renewable energy sources as compared to conventionally used nonrenewable energy sources in sensor nodes. In this paper, adaptive topological knowledge (ATK) algorithm is used to periodically and locally determine the topological knowledge range (KR) of each solar-powered node, based on an estimated energy...
ZigBee low power wireless networks, as the fittest plane for WSN in existing, are paid attention to increasing by people. In this paper, we present the topology of tree cluster network, by analyzing the algorithm for routing we propose a method that the first receiving are the best route to implement message routing. To demonstrate its effectiveness, we form a tree cluster network and validate process...
