Wireless sensor network is one of the developing ranges of research in present situation. A Wireless sensor network comprises of geographically dispersed self-governing tiny sensor nodes with little battery life to screen and control over the physical parameters or ecological conditions, for example, temperature, sound, pressure, humidity and so on and this data is gone by the sensor nodes in the...
Wireless sensor networks are widely used both in the civil and military fields. Large-scale sensor nodes are usually deployed in potentially adverse or even hostile environment, so the security in these networks is very important. The design for key management protocol is one of the most important aspects and basic research field of secure wireless sensor networks. The key management in wireless sensor...
In this paper we put forward a kind of secure LEACH routing protocol (SC-LEACH) based on low-power cluster-head selection algorithm. This protocol gets the total number of all nodes by their collaboration in selecting, to precisely calculate the present thresholds with which the cluster-heads is generated. Consequently, the probability of producing optimal cluster-heads in each round is the biggest,...
