An adhoc network is a dynamic multi-hop wireless network established by a group of mobile nodes on a shared wireless channel without any infrastructure. Efficient clustering and routing in adhoc networks has been a topic of research in the past few years. The literature that deals with adhoc routing identifies two types of networks viz. hierarchical routed networks and flat routed networks. While the former creates a hierarchy among the nodes the latter treats all nodes equally. Most hierarchical clustering architectures for mobile radio networks are based on concept of cluster head (CH) [1,2,3]. In most of the proposed methods in hierarchical (clustered) networks, much thought has not been given for the selection of the CH. In order to design a stable network we need to look after features that the clusters should suffice. In  CH is selected based on a node identifier and thus may not be spatially and temporally suitable. The concept of associativity (relative stability of nodes) was used to get long live routes in routing . Associativity provides temporal stability but not spatial. By up-to-date GPS system, location information is available to different mobile computing platforms . Therefore, we intend to address the above-mentioned issues and propose to design a novel location-aware clustering strategy. The cluster formation scheme should form clusters based on the spatio-temporal stability of the mobile nodes forming the adhoc network.
