Abstract:
This work elaborates on the real-time implementation and comparative evaluation of an Energy-efficient scheme for sharing resources using the MICA2dot wireless nodes/motes. The proposed scheme allows the nodes to sleep adaptively according to the volume of incoming traffic, offering Energy Conservation (EC) to the moving nodes. Nodes that are exchanging delay sensitive/constrained resources apply the one-level Backward Traffic Difference (BTD) scheme or the two-level BTD, according to delay transmission and capacity criteria, in order to enable nodes to sleep, based on their activity and their admitted traffic. The incoming traffic impacts the Sleep-time duration of the node by using traffic’s backward difference in order to define an adaptive Sleep-time duration for each node. The proposed scheme is being evaluated through real-time implementation by using MICA2dot wireless motes, which are exchanging resources in a Mobile Peer-to-Peer manner using certain motion pattern. Performance evaluation and the extracted results validate the scheme’s efficiency for minimizing the Energy Consumption in real-time. In addition, comparative performance evaluations with other similar schemes show the efficiency of the proposed research approach. The framework of this paper maximizes further the efficiency and reliability of the resource exchange process of the nodes, while it minimizes the Energy consumption.
