Wireless Sensor Networks (WSNs) are an emerging technology, recently finding extensive application in scientific and military surveillance. Typical WSNs comprise hundreds of tiny, severely energy constrained sensor nodes that are statically deployed to collaborate and accomplish common application tasks. The effectiveness of a WSN depends on its efficiency in using the limited energy supply, and thus, energy conservation is a forefront research area for sensor network technology. WSNs are largely characterized by short-range multi-hop radio communications, which provides abundant scope for routing-level energy conservation schemes. WSNs are often densely deployed for robustness against node and link failures, and only a sub-set of nodes is required to be operating at any instant to satisfy the application needs. This work aims to exploit such connection redundancies in sensor deployments, using network level adaptations, and achieve energy efficiency.
