In order to solve the shortcomings of traditional resource discovery mechanism. Many sophisticated strategies are implemented to ensure that the grid resource discovery service has good scalability and efficiency. Nodes are divided into different domains, and we use improved distributed hash table technology to achieve higher local routing efficiency; the combination of the tree overlay network and...
To enhance power efficiency of battery powered wireless access devices, the behaviors of the mobile stations (MS) working in the sleep mode operation in IEEE 802.16e was researched with a method of the Markov chain model. By exploring the relationship among traffic load, power consumption and delay, we present a cross-layer design-based algorithm to tune the initial sleep window according to the randomization...
In this paper, we propose a dynamic traffic load-aware sleep mode operation to improve the power efficiency of battery powered IEEE 802.16e devices. By analyzing the sleep mode operation with a Markov chain model, we explore the relationship among traffic load, power consumption and idle check time. Based on the analytical results, we propose a dynamic algorithm to tune the idle check time according...
