Therefore, power consumption of network operations is critical and subject to optimization. Approach: A novel hybrid PSO was proposed for solving the minimum power multicast problem in wireless ad-hoc networks. The MPM … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 6,809 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Channel Adaptive Energy Efficient and Fair Scheduling Media Access Control Protocol for Mobile AdHoc NetworksP. Priakanth, P. ThangarajProblem statement: A major drawback in the existing protocols in dealing with energy management issues is that the time varying nature of the wireless channels among the ad hoc nodes is ignored. Approach: This study proposed a channel adaptive energy efficient Medium Access Control (MAC) protocol, for efficient packets scheduling and queuing in an ad hoc network, with time varying … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,556 accessesView PDFCite
Research ArticleOpen accessIn the abstractTCP Optimal Performance in Wireless Networks ApplicationsEmad Qaddoura, Abdelghani Daraiseh, Wesam Al Mobaideen et al.Mobile Ad Hoc Network (MANET) consists of dynamic topology as nodes in the network are mobile, and connected via wireless links. The nodes are grouped in clusters for the purpose of routing. Nodes within the cluster communicate directly. However, nodes communicate outside the cluster through a centralized node that is called a clusterhead. An elected clusterhead is assigned for communication … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,417 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Cross-Layered Path Stability Based Routing Protocol for WiMAX NetworksM. Deva Priya, M. L. ValarmathiIn IEEE 802.16, a Subscriber Station (SS) is battery powered with limited capacity. A SS can be made to operate for longer durations by deploying power saving features or by using relay stations. Multi-hop communication conserves power, but finding an optimal path to the destination is monotonous. Path stability indicates how stable a path is and how long it can … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 6,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Approach for Rate Adaptation in Mobile Adhoc NetworksPalaniammal Senniappan, Suganya SubramaniamA Mobile Ad hoc Network (MANET) is a collection of mobile nodes with no fixed infrastructure. The absence of central authorization facility in dynamic and distributed environment affects the optimal utilization of resources like, throughput, power and bandwidth. Rate adaptation is the key technique to optimize the resource throughput. Some recently proposed rate adaptations use Request to Send/Clear to Send … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,673 accessesView PDFCite
