新的自适应MANET服务发现区域策略——ASDZP

为提高MANET服务发现的稳定性和高效性，分析了现有区域自适应协议的特点，提出了一种自适应服务发现区域策略。该策略以区域内节点平均稳定性和平均活跃度作为服务区域大小的决定因素，有效地减少了区域内不稳定节点的数量，提高了区域内服务节点的比例，增强了区域整体的服务提供能力。经理论分析及仿真实验验证，该策略比传统的区域路由协议（ZRP）服务发现策略具有更小的控制开销和能耗以及更短的端对端延时。

ASDZP: New regional strategy for adaptive MANET service discovery

To improve the stability and efficiency of the service discovery in MANET, characteristics of the existing adaptive zone protocols are analyzed, a novel To improve the stability and efficiency of the service discovery in Mobile Ad Hoc Networks (MANET), the characteristics of the existing adaptive zone protocols were analyzed, and a new regional strategy for adaptive MANET service discovery was proposed. This method regulated the radius of service discovery zone according to the average stability and activity of nodes in the zone, reducing the number of the unstable nodes and improving the proportion of the service nodes in the zone. The ability of overall regional service was enhanced. Results of the formulas and simulation indicate the strategy provides better performance than the traditional service discovery based on Zone routing Protocol (ZRP) in terms of control overhead and energy consumption, and decreases the average delay effectively.
