Enhancement of QoS in Mobile Network through Channel Allocation using Software Agents
Nitin Muchhal, Swapnil Jain, Yogesh Sharma · 2011
In the last two decades the demand for mobile hosts is increasing rapidly. One of the biggest challenges in cellular systems is to fulfill the mobile user demand under the constraint of the limited spectrum. Some of the most common methods to increase the channel allocation and utilization are resource allocation schemes. Various channel allocation schemes have been proposed to provide Quality of Service (QoS) and efficient channel utilization in cellular networks. This paper proposes architecture of Multi-agent system consisting of software agents to implement distributed dynamic channel allocation strategy. The strategy is based on the channel reassignment within the cell boundary and chained channel borrowing in neighboring cell areas. The QoS parameters analyzed are Call dropping probability and Call blocking probability. transmission. An overall cellular network contains a number of different elements from the base transceiver station (BTS) itself with its antenna back through a base station controller (BSC), and a mobile switching centre (MSC) to the location registers (HLR and VLR) and the link to the public switched telephone network (PSTN). Another important aspect of cellular telephony is unlimited mobility. The user can be anywhere within the coverage area of the network, in order to be able to communicate. The cellular network interfaces with the PSTN, as well as with other wireless systems.
