“…The flow priority is adjusted by adjusting the duty cycle of sleep time of active nodes to avoid eternal waiting by low traffic nodes. Another research work is proposed in [16] to effectively manage the power requirements for communication. An integer linear program (ILP) formulation that jointly optimizes channel allocation and power control for incoming calls, based on the carrier-to-interference ratio (CIR) is presented.…”

WMNs (Wireless mesh networks) have evolved as a leading technology for next-generation wireless networks. The benefits of WMNs over other wireless technologies have enhanced its multi-facet growth and stimulated a variety of applications. However, there exist several issues in the WMNs, power control being one. In order to offer a detail perspective of the proficient power control in WMNs, this paper presents a thorough study of available power distribution algorithms for WMNs. It is observed that most research work has been based on infrastructure based WMN.

“…The idea behind power control schemes is based on the fact that the CIR at a wireless terminal is direct ly proportional to the power level of the desired signal and inversely proportional to the sum o f the power of co-channel interferers. There are many schemes of channel allocation based on power control are proposed in literature [138,[140][141][142].The ma in objective of power control schemes are to, try to reduce the overall CIR in the system by measuring the received power and increasing/decreasing the transmitted power in order to maximize the minimu m CIR in a given channel allocation o f the system [138,140,142] , so that capacity of the system can be increased. The purpose of different power control schemes is to adjust a trade-off between the change of power level in opposite directions.…”

“…In paper [141] a scheme based on an integer linear program (ILP) formu lation has been used to optimally solve the combined channel assignment and power control problem in wireless cellular networks. This scheme ensures that the CIR requirements are met, not only for the new incoming call but also for all ongoing calls using the same channel.…”

In recent years, we have witnessed a huge interest in the study of channel allocation and handoff strategies for cellu lar systems to ensure continuous services that guarantee QoS to mobile users. In this paper, we have a detailed d iscussion of different categories of wireless channel allocation schemes. The basic purpose of the study is to provide a comprehensive review of d ifferent categories of channel allocation algorith ms in cellu lar systems and to recommend future direct ions of research in the area. The paper g ives a survey of published papers for discussing channel allocation schemes for cellular system. The QoS is always a major concern fo r the services offered through cellular systems and it is observed that there are always trade-offs among various parameters of the QoS of these services. There are many published papers which have taken care of d ifferent QoS parameters such as call b locking probability, call dropping probability along with other performance parameters. This paper provides details of the d ifferent categories of channel allocation schemes including static channel allocation, dynamic channel allocation and hybrid channel allocation studied in literature. A lso in this paper, we explore the different channel allocation strategies, including the scenarios in which channel allocation strategies based on centralized channel control, distributed channel control, mutual exclusion algorith ms and genetic algorith ms, are used. Also, we have summarizes trade-offs between different channel allocation schemes in terms of their co mplexity and performance. In this paper, channel allocation in different context of co mple x situations such as the ones arising in offering mu ltimed ia based services and other arising in the channel allocation for mobile base station systems and use of power management in channel allocation are exp lained. This paper also examines different handoff handling provision and prioritizat ion schemes proposed in the literature for cellu lar systems.

The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adjust threshold to control the admission. To give the priority to handoff calls over the new calls, the provision of guard channels and subrating scheme is taken into consideration. The handoff voice call may balk and renege from the system while waiting in the buffer. An iterative algorithm is implemented to generate the arrival rate of the handoff calls in each cell. Various performance indices are established in term of steady state probabilities. The sensitivity analysis has also been carried out to examine the tractability of algorithms and to explore the effects of system descriptors on the performance indices.
