Networking issues in large microsensor nets

Microsensor networks have been proposed for remote sensing applications. These ad-hoc networks may have thousands of nodes; apart from the important scaling issues, interesting problems arise in designing protocols and routing algorithms that maximize the lifetime of the network subject to constraints on bandwidth and energy and complexities due to mobility and changing topology. The network must be able to self-configure and self-localize. This paper gives an overview of the issues involved and then focuses on using multiple network reconfigurations and local fusion to increase the overall system lifetime.
