چکیده
Rapid growth in telecom industry searching for new methods provide the better service to their customer here implementing proposes a multihop dynamic channel assignment (MDCA) scheme for time division multiple access (TDMA)-based multihop cellular networks. The proposed MDCA assigns channels are observed in ofdma system to the calls based on interference information in surrounding cells, provided by the Interference Information Table (IIT) in the network. Two different channel searching strategies, Sequential Channel Searching (SCS) and Packing based Channel Searching (PCS), for use in MDCA are proposed and studied. A channel reassignment procedure to further enhance the performance is also investigated. Simulation results show that MDCA significantly improves the system capacity. Furthermore, the MDCA can efficiently alleviate the call blocking in hot-spot cells.

Distributed Dynamic Channel Assignment for Multi-Hop DS-CDMA Virtual Cellular Network
In this paper, the channel segregation dynamic channel allocation (CS-DCA) scheme is applied to a multi-hop DS-CDMA virtual cellular network (VCN). After all multi-hop routes are constructed over distributed wireless ports in a virtual cell, the CS-DCA is carried out to allocate the channels to multi-hop up and down links. Each wireless port is equipped with a channel priority table. The transm...

In this paper, we consider the call admission problem in cellular network with two classes of voice users. In the first part of paper, we introduce a two-threshold guard channel policy and study its limiting behavior under the stationary traffic. Then we give an algorithm for finding the optimal number of guard channels. In the second part of this paper, we give an algorithm, which minimizes th...
متن کاملA Multihop Dynamic Channel Assignment Scheme For Cellular Network
A multihop Dynamic Channel Assignment Scheme is proposed here for Multihop Cellular network. The proposed scheme splits the cell into microcell and macrocell to accept and complete the call as single hop, two hops, or three hops call. The radio resources are assigned to each call based on the interference information in the surrounding cells, stored in Interference Information Table at MSC. Two...

متن کاملA dynamic channel assignment scheme for clustered multihop cellular networks
Whereas cellular systems have traditionally adopted single-hop transmissions between the mobile station (MS) and the base station (BS), researchers expect multihop transmission to be utilised in the future. Cellular systems present several challenges, such as channel assignment, which are exacerbated by multimedia service traffic and an increasing number of subscribers. Recently, a clustered mu...
