除了以上分析的負載均衡方法外,還有一些問題亟待研究,例如:負載均衡優(yōu)劣的度量、流量分配的穩(wěn)定性、流量的分割和負載均衡對路由的影響以及由于流量分割產(chǎn)生的亂序現(xiàn)象對TCP性能的影響、節(jié)點如何跨層感知負載情況并形成基于跨層協(xié)作的負載均衡算法等。除此之外,尚有一些關(guān)鍵技術(shù)問題有待進一步解決,如WMN的QoS保障、分布式網(wǎng)絡(luò)管理、控制機制、WMN安全機制等問題。 4th Annual IEEE Communications Society Conference on Sensor, Mesh and Ad Hoc Communications and Networks( SECON 39。 10th Annual International Conference on Mobile Computing and Networking (MOBICOM39。 06), Nov 27Dec 1, 2006, San Francisco, CA, USA.
