Cross-Layer QoS Architecture with Multipath Routing in Wireless Multimedia Sensor Networks

摘要: This paper proposes a multipath routing algorithm using cross-layer architecture in wireless multimedia sensor networks (WMSNs) to provide QoS guaranteed delivery of data. When the proposed this study establishes path from source destination node, it takes into account distance sink and energy level link quality neighbor nodes. It also specifies service pattern depending on traffic pattern. By doing this, can realize differentiated with data transmission. enables use multiple paths when delivering helps alleviate power consumption concentration that happens at particular set nodes along frequently selected route. Concentrated cause another problem, is, route reconfiguration due failure. The effectively avoids problem. As result, improve reliability network by increasing packet transmission rate reducing loss delay.
