Directional mobility based nearest neighbor clustering for critical node detection in MANETs

Critical nodes are severe threats to network performance. Critical nodes when deteriorating would disturb the communication in the network. Presence of such critical nodes/links in MANETs should be detected in advance to retain the prevailing communication setup. This paper discusses a short survey on the existing clustering algorithms utilized for routing in MANETs. This paper also proposes mobility based clustering for critical node detection. The evaluation of proposed Mobility based NN clustering (MNN) protocols for critical node detection is on par with other unequal clustering protocols. The results show a promising improvement in network performance ignoring the efficiency of cluster head.
