Since there is no central management center in the MANETs, nodes need to self-manage service provided by other nodes. To pursue maximal utilities, they should be able to negotiate autonomously for services, e.g., packets transmission, information share. While some selfish mobile nodes in MANETs are unwilling to provide services for other users, it directly leads to serious decline in network performances...
The growing concern of global climate change calls for a revolutionary change on the way of utilizing the energy. In terms of the ICT industry, energy efficiency needs to be considered as an important metric to evaluate a communication system, besides the conventional metrics such as quality of service, bandwidth efficiency, etc. Research should be done to raise the energy efficiency of communication...
This paper studies task allocation in cluster-based Wireless Sensor Network (WSN) using negotiation model. We study both the negotiation reasoning model and the negotiation protocol for task allocation to achieve energy efficiency while balancing nodes energy. Reasoning model determines the offer generate scheme and gives control over negotiation process. A time depending Boulware function is used...
High energy consumption at mobile devices is a critical issue for end users to access and enjoy high data-rate multimedia applications and services in Wireless Local Area Networks (WLANs). This paper develops an analytical framework for analyzing and comparing the energy efficiency performance of IEEE 802.11n Medium Access Control (MAC) protocol and a Busy Tone Based Cooperative MAC Protocol(namely...
The aim of this paper is to provide an energy efficiency analysis of the Cooperative Access with Relay's Data for Multi-rate wireless local area networks (WLANs), named CARD protocol at the Medium Access Control (MAC) layer taking into account the impact of both transmission channel states and multi-rate transmission. Simulation results closely match the analytical results confirming the effectiveness...
