We analyze economic e ciency and equilibrium properties in decentralized task allocation problems involving hierarchical dependencies and resource contention. We bound the ine ciency of a type of approximate equilibrium in proportion to the number of agents and the bidding parameters in a particular market protocol. This protocol converges to an approximate equilibrium with respect to all agent...
In optical burst-switched networks, data loss may occur when bursts contend for network resources. There have been several proposed solutions to resolve contentions in order to minimize loss. These localized contention resolution techniques react to contention, but do not address the more fundamental problem of congestion. Hence, there is a need for network level contention avoidance using load...
This paper deals with coexistence issues among contention-based heterogeneous wireless networks that have different transmission power and/or coverage. We show that the existing carrier sensing multiple access mechanism, which is a prevailing contention-based protocol, results in a significant unfairness of channel sharing. We analyze the reasons of such unfairness by considering the mutual eff...
The IEEE 802. 15. 6 is a new communication standard on Wireless Body Area Network (WBAN) for short-range, wireless communications in the vicinity of, or inside a human body. It is used for medical and non-medical applications. The IEEE 802. 15. 6 draft defines a Medium Access Control (MAC) layer compatible with several Physical layers (PHY), it also specifies two main channel access modes; cont...
