When wireless devices share resources following the opportunistic manner, the resource exchange process faces several connectivity challenges that need to be faced via reactive combinatorial practices. This work proposes a scheme for sharing resources using the opportunistic networking paradigm whereas, it enables Energy Conservation (EC) by allocating Real-Time Traffic-based dissimilar Sleep/Wake schedules to wireless devices. The scheme considers the resource sharing process which according to the duration of the traffic through the associated channel, it impacts the Sleep-time duration of the node using two different perspectives: the recoverable cached capacity and the node’s self-monitored traversed traffic. For both cases the paper examines the traffic’s backward difference in order to define the next Sleep-time duration for each node. The proposed scheme is being evaluated through Real-Time implementation by using dynamically moving MICA2dot wireless nodes which are exchanging resources in a Mobile Peer-to-Peer manner. Various performance metrics were considered for the thorough evaluation of the proposed scheme. Results have shown the scheme’s efficiency for enabling EC and provide a schematic way for minimizing the Energy Consumption in Real-Time, in contrast to the delay variations between packets; whereas the proposed scheme aims at maximizing the efficiency of resource exchange between mobile peers.
