Energy Efficient Resource Distribution for Mobile Wireless Sensor Networks

Abstract

This work addresses the problem of energy efficient management of mobile resource distribution in Wireless Sensor Networks (WSN), subject to Quality of Service (QoS) constraints. Monitored phenomena may require an increased coverage within a particular area and we present novel methodologies for optimizing the "bargaining stage" when deciding how to select the mobile resources to be re-located in response to such events. Our experimental results demonstrate significant energy savings, both in terms of communication overheads and maintenance of the hierarchical routing structures, as well as the quality assurances in terms of the turnaround time.

Bypassing holes in sensor networks: Load-balance vs. latency

“…Our main thrust is on considering multiple holes in the WSN. Among the other few extensions that we are also working on, one is focusing on including the mobility of the sink-nodes in the model [53,54] and investigate how that would impact the balance between latency and prolonging the lifetime of boundary nodes. The other extension considers the impact of having heterogeneous nodes and location-uncertainty in tracking scenarios [55,56], and varied routing algorithms towards multiple holes situations.…”
