Wireless sensor networks have serious energy constrain, since external power sources are typically unavailable. Typical wireless sensor nodes use batteries or fuel cells as the power source. The primary design goal of routing protocols is to efficiently use the energy of sensor nodes and prolong the survival time of the network. This paper analyzes the classical clustering routing protocol LEACH and...
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,...
