Abstract
W-CHAMB (Wireless Channel-oriented Ad-hoc Multi-hop Broadband) is an innovative MAC scheme for beyond 3G wireless systems. It can operate under multi-hop and ad-hoc environment and is able to provide QoS (Quality of service) guarantee. The basic ideas of the scheme are using energy signals to contend in order to get the access right and transmitting data by means of periodic time slots (TDMA channels). However, synchronization is a headache issue for distributed TDMA systems. This paper introduces a solution for the problem. A modification of the MAC frame structure introduced in former publications enables to implement the synchronization function. The system is easily configured to support wireless nodes up to 3000 for one-hop ad-hoc network and the extended algorithm could support multi-hop scenarios. An event driven stochastic simulator has been developed to verify the ideas. The proposed scheme can also be used to solve the synchronization issue for other TDMA systems with distributed control, like wired TDMA distributed systems.
