Wireless Sensor Networks (WSNs) is getting larger in size and coverage area. Currently, some WSNs are having thousands of sensor nodes deployed to monitor critical regions or watch out for ecological phenomenon. Large Scale WSNs place strong challenges on many aspects of network modeling, deployment, protocols, and data gathering. Existing policies and techniques in WSNs need to be scaled efficiently as the average deployable network size increases.
In this study we propose an efficient clustering protocol called AMHC used for resource discovery in large scale Mobile Ad hoc Networks (MANETs). AMHC is an Adaptive Multi-Hop Clustering generating several non-overlapping network localities (clusters) with explicit elected cluster-heads. Every cluster member is on average d hops away from its cluster-head, where d is an integer parameter for the protocol. The generated set of clusters are highly stable and has low restructuring frequency that takes into consideration the dynamic network topology due to nodes mobility and depleted energy.
