Mobile wireless networks have fascinating characteristics of rapid deployment and network connectivity anywhere and anytime. Due to their very nature of being mobile, grievous security issues may arise, for which some homogeneous solutions have already been proposed. However, each node may have its own security requirements depending on the available resources and the services or applications it uses...
In this paper, we study the delay-constrained information coverage problem in mobile wireless networks. Motivated by real application needs, our formulation takes advantage of the node mobility for information collection, which takes place when a node moves into the proximity of stationary base stations. To the best of our knowledge, we present the first formulation for the delay-constrained information...
We propose a game-theoretic framework for quality-of-service (QoS) aware resource competition among coexisting wireless links in mobile wireless networks. The senders of wireless links use the constant transmit power and then the wireless resources of interest is characterized by time-slot length. Multiple wireless links will use the limited wireless resources through a time-slot competition game...
In the modern era the uses of wireless devices are becoming ubiquitous and these networks have become an increasingly important part of global communication architecture. Most of the wireless networks have fixed infrastructure and the need for mobile wireless networks are growing rapidly, which requires higher data rates. Due to high data rate in wireless networks the TCP performance has a broad and...
We compare the performance of three handoff protocols, namely Mobile IP, Fast Handoff and mSCTP. Among the three schemes, Mobile IP suffers from the lowest data throughput and longest handoff latency. Fast Handoff can perform better, provided that the mobile node can handoff to the new base station at an appropriate time instant when data forwarding between network routers begins. mSCTP supports multihoming;...
This paper describes a communication model in a two-dimensional grid for mobile wireless networks and shows how to optimally solve some decision problems related to the model. We show that user communication problem (UCP) and source reachability problem (SRP) can be most efficiently solved in polynomial time. Asymptotically time-optimal algorithms for solving these problems are also presented.
We propose and analyze spillover-partitioning call admission control (CAC) for servicing multiple service classes in mobile wireless networks for revenue optimization with quality of service (QoS) guarantees. We evaluate the performance of spillover-partitioning CAC in terms of execution speed and optimal revenue obtainable by comparing it with existing CAC algorithms, including partitioning, threshold,...
In this contribution, motivation and operating guidelines for quality of service (QoS) provision and control in wireless communications are discussed and investigated. In the last years, there has been an explosive growth in mobile communications providing in the next future the transmission rates required by most potential users, but the practical question arises of what type of services can be performed,...
