In wireless ad hoc networks, co-channel interference can be suppressed effectively through proper integration of channel assignment (CA) and power control (PC) techniques. Unlike centralised cellular networks where CA and PC can be coordinated by base stations, the integration of CA and PC into infrastructureless wireless ad hoc networks where no global(More)
Resource allocation in wireless ad hoc networks is usually modelled in a non-cooperative game theoretic framework with the objective of maximising individual utility. However, the selfishness of autonomous users under such framework may lead to throughput unfairness which only benefits certain users. To alleviate this unfairness problem, the authors propose(More)
– Community Wireless Mesh Networks (WMN) is a paradigm in wireless communication of 21 st centuary as means of providing high speed braodband access. Uncooperative nodes, both selfish and malicious proves to be a significant threat in Community WMN that require a solution independent of routing protocols being used. We propose to implement Modified PIFA(More)
In this paper, we focus our study on energy-effkient routing algorithms. We study an algorithm called energy-eficient tree-based routing, which is based on a tree-like topology rooted at a fixed base station (sink node) of the network with a fixed 2-dimensional (2D) grid topology. The performance of this algorithm is assessed by computer simulation and is(More)
This article presents a subcarrier allocation scheme based on a Blotto game (SABG) for orthogonal frequency-division multiple access (OFDMA) networks where correlation between adjacent subcarriers is considered. In the proposed game, users simultaneously compete for subcarriers using a limited budget. In order to win as many good subcarriers as possible in(More)
