A quality of service analysis of CDMA-based AODV routing protocol for ad-hoc wireless networks

Ad-hoc wireless networks are the networks without an infrastructure. Infrastructure-less mobile networks have no fixed routers or base stations. All nodes in these networks are capable of movement and can be connected dynamically at any time. The issue of routing packets effectively between any nodes in an ad-hoc network is a challenging task. A path that was considered optimal at a given time point may not be working after a few moments. Moreover the bandwidth available between a link may not remain the same since every node in this kind of network is behaving as a router and may experience drastical increase in throughput and traffic load. For the purpose of quality of communication, bandwidth reservation within ad-hoc wireless network nodes may prove promising as a solution to this problem. This thesis presents an approach to reserve bandwidth available utilizing CDMA of bandwidth to the Ad-hoc Distance Vector Protocol for the ad-hoc wireless networks. Various quality of service issues are discussed and are tested for optimal performance for AODV routing protocol. A QoS performance comparison based on mobility, congestion and throughput is made between AODV and CDMA based AODV mobile routing protocols.
