In this paper, we focus our study on energy-efficient routing algorithms. We study an algorithm called energy-efficient 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)
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)
Agricultural monitoring using wireless sensor networks has gained much popularity recently. In this paper, we review five existing flat-tree routing algorithms and proposed a new algorithm suitable for applications such as paddy field monitoring using wireless sensor network. One of the popular data collection methods is the data aggregation approach, where(More)
The feasibility of providing broadband wireless access (BWA) to vehicular passengers by providing a number of Wi-Fi (IEEE 802.11b) access points (APs) along roads is investigated. For BWA to vehicular passengers to become reality an array of technological challenges need to be addressed. In this paper, some unique features and challenges that distinguish(More)
Community Wireless Mesh Networks (WMN) is a paradigm in wireless communication of 21<sup>st</sup> centuary as means of providing high speed braodband access. Un-cooperative 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(More)
This article presents a subcarrier allocation scheme based on a Blotto game (SABG) for orthogonal frequencydivision 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)
