Özet
Wireless Multimedia Sensor Networks (WMSNs) have recently attracted more attention and have contributed to new potential wireless sensor network (WSN) applications such as border surveillance, battlefield monitoring, target detection, target tracking and habitat monitoring. WMSNs carry heterogeneous traffic with different urgency and quality of service (QoS) requirements. While the need to minimize energy consumption is important in WSNs, offering QoS for multimedia transmission is a challenging issue due to resource constrained nature of sensor nodes, unreliable wireless links and unpredictable environments. Currently, there is a need for a new QoS aware, priority based cross layer Medium Access Control (MAC) protocol on WMSNs. Proposed new two tiered service differentiation mechanism and data rate adjustment scheme provides 8.7 times lower average end to end delay for urgent real time video traffic while providing lower end-to end delay for each urgent traffic class. Proposed mechanism has been focused on QoS provisioning at MAC layer for urgent traffic on especially military applications providing data rate adjustment by application layer.
