Wireless sensor networks and traditional wireless networks have significantly different characteristics of performance and technical requirements. The traditional wireless networks MAC (medium access control) protocol can not be applied to sensor networks, suggest a number of related agreements against the various characteristics of sensor networks, this paper presents an adaptive cross-layer design...
Article proposes the existing problems of the QoS multimedia services in IEEE802.16, analyzes the disadvantage and advantage of current bandwidth scheduling strategy based on IEEE802.16. An improvement strategy of IEEE802.16 PMP network model is proposed based on existing strict priority scheduling strategy. Finally, through the simulation data, we proof the strategy can ensure the QoS performance...
With the rapid development of information technology, wireless network technology becomes more and more widespread, transmission efficiency of wireless network has been a research focus. This paper firstly has discussed the principles of aggregation of the use of packet technology in the feasibility of the use of WLAN, and specific circumstances of the packages fusion method by NS2 simulation achieved...
