A load balancing strategy using dynamic channel assignment and channel borrowing in cellular mobile environment

Abstract

A simple load balancing technique is proposed. It is basically a combination of both the dynamic channel assignment and channel borrowing techniques. All the cells of the system are divided into six groups, each group under one mobile switching centre (MSC). Initially a fixed number of channels are assigned to each cell under each mobile switching centre. Finally the channels are distributed among the cells as per their requirement. In the case of sudden channel demand under one mobile switching centre, the cell which needs more channel can borrow a channel from one of its compact pattern cells belonging to the same group (to be defined) with it by exchanging a negligible number of messages among the different components of the network. If there is no probable lender cell in the group, the MSC of the borrower cell can lend it from another MSC.
