“…and report the collected data to the sink station by using multi-hop wireless communications. The clustering concept, that means grouping nodes which are close to each other, has been studied largely in ad-hoc networks [2,3,4,5,6,7,8] and recently in WSNs [9,10,11,12,13] where the purpose in general is to reduce useful energy consumption and routing overhead, however, cluster-heads must be selected carefully and diligently. Recent research studies recognize that organizing mobile WSNs, in the sense defined above, into clusters by using a clustering mechanism is a challenging task [9,10].…”
