QoS-Aware Routing Based on Adaptive-Gossip Algorithm for Conserving Resource in Ad Hoc Wireless Networks

In ad hoc wireless networks (AWNs), the provision of Quality of Service (QoS) guarantees is much more challenging than in conventional wireless networks, mainly due to node mobility, multihop communications, contention for channel access and a lack of central coordination. Typically multimedia applications have delay-sensitive and high bandwidth requirements, especially for shared wireless channels by adjacent nodes and dynamic network topology in AWNs. In recent years, QoS routing has received increased attention because it plays an important role in selecting a path satisfy QoS requirements and achieving global efficiency in resource utilization. Many proposed solutions focus on two metrics: high performance throughput and delay guarantee based on providing QoS requirements without conserving network resources in densely deployed AWNs. Therefore, we develop QoS-aware routing protocol using our adaptive-gossiping algorithm which can efficiently deliver packets with minimum communication overhead and use less network resources while ensuring high throughput and low end-to-end delay.
