I. INTRODUCTIONWith rapid advancement of communication technology, the number of mobile users continues to grow which demands more cellular capacity to fulfill the expected high quality voice communications and high-speed multimedia data transfer services. However, the frequency spectrum is always limited. This has resulted in utilization of radio resources. The use of radio resources increases cellular capacity by dividing a large cell into many smaller cells and then each cell reuses the channel spectrum. In a Code Division Multiple Access (CDMA) cellular system, such as second generation (2G) CDMA or third generation (3G) Wideband Code Division Multiple Access (W-CDMA) system, a small cell size allows a higher interference margin [1] to encounter higher noise level, resulting in a high data rate transmission. This needs that more number of Base Stations (BSs) is to be deployed. Raising more BSs involves higher cost in terms of infrastructure and administration. These networks also suffer Kishana R.

“…By splitting the cell into more number of smaller cells, the data packets reach the destination through intermediate nodes or the relay nodes, this type of Network is called the Multihop Cellular Networks (MCN). Several recent proposals [5], [7], [8], [11] and [12] look at multihop cellular networks (MCNs), which are designed based on the idea of using mobile and/or fixed terminals to relay signals from source nodes to BSs or destination nodes. The benefit of conventional Single hop Cellular Networks (SCN) is preserved by MCN, where the service Infrastructure is constructed by fixed bases, and it also incorporates the flexibility of ad-hoc networks where wireless transmission through mobile stations in multiple hops is allowed.…”

Multihop cellular Networks has the problem of channel assignment when connections are established between the adjacent cells and due to more number of nodes in the path between the sender and the receiver relay delay occurs and cause unwanted delay in the overall end to end communication. To overcome the problems associated with the relay delay and the overall performance in the Multihop Cellular Networks a new protocol is introduced which combines the merits of both the modified Minimum Slot Waiting First Algorithm and the modified Distance Vector Routing. Through the proposed new protocol, we can provide solution for the problem of routing and relay delay in Multihop Cellular Networks and the performance of the packet transmission can be improved.

“…To achieve high cell capacity without sacrificing the coverage or network reachability, some MCN proposals, e.g. ad hoc cellular relay architecture (A-Cell) [8], assume a small cell size and a dense network. A small cell allows high cell capacity whereas a dense network provides sufficient relaying nodes for relaying signals.…”

In 3G-based multi-hop cellular networks (MCNs), the cell size affects the cell capacity and the network reachability, which in turn affect the total demand of source nodes that can be served or the system throughput. Improper cell size assignment greatly affects the performance of the networks. To address the cell size issue, we recently proposed the Optimal Cell Size (OCS) scheme to find optimal cell sizes to maximize the system throughput for a 3G TDD W-CDMA MCN. Although OCS provides an optimal cell size solution, it is computationally expensive. In this paper, we propose a heuristic cell size scheme, called Small Cell Size First (SCSF), which is more efficient and provides good results in terms of throughput compared to the optimal solutions provided by OCS. SCSF outperforms the fixed small cell size (SCS) multi-hop case when the network is sparse and the large cell size single-hop case regardless of the network density.
