Resource Management Technique for QOS Support in Hybrid Wireless Network

Wireless hybrid network that integrates a mobile wireless ad hoc network (MANET) and a wireless infrastructure network has been proven to be a better alternative for the next generation wireless networks. The Hybrid wireless network has higher capacity than cellular networks. It increases flexibility and reliability in routing. It has better coverage and connectivity. Hybrids networks inherit invalid reservation and race condition problems in MANETs by directly adopting resource reservation-based Quality of Service (QoS) routing for MANETs. This affects the quality of service in hybrid network. Most of the current work in hybrid networks focus on enhancing quality of service but cannot reduce the transmission time and traffic between sender and receiver in the network. In this paper, an ADAPTIVE RESOURCE MANAGEMENT approach is proposed to enhance the QoS by reducing the transmission time and traffic in hybrid networks. Adaptive resource management incorporates six algorithms: 1) Admission controller to select qualified neighbor for packet forwarding, 2) Encryption algorithm to encrypt the content of the source node, 3) Channel assignment to reduce traffic in the network, 4) Packet scheduling algorithm to further reduce the transmission delay, 5) Packet resizing algorithm that adaptively adjusts segment size according to node mobility, 6) a redundancy elimination algorithm to eliminate the redundant data in the packet.
