Abstract
This paper presents a nurumum hop routing algorithm for the multihop cellular CDMA network. A mechanism to update routing paths in case of network topology change is also developed. Mobile terminals will be separated into two groups and each group will only transmit on one of two timeslots so that terminals do not have to transmit and receive simultaneously on the same frequency band. The routing algorithm in this paper is designed in order to optimize criteria including SNIR, delay, power consumption, and network lifetime. Simulation is used to evaluate these criteria for the multihop cellular network and its performance is compared with the traditional cellular network. Simulations show that the total power consumption in the multihop cellular network is much lower than a traditional cellular network with a capacity that is nearly as high. Simulations also show that the network lifetime of the multihop cellular network is much higher than that of a traditional cellular network.
Highlights
This paper presents a nurumum hop routing algorithm for the multihop cellular CDMA network
All transmissions in the multihop cellular network were made within timeslots and the base station was used to relay all packets to their destination
It was shown in this paper that when using minimum hop routing, a much lower power consumption can be obtained for the multihop cellular network than for a traditional single hop cellular network
