Recent Trends in Wireless Multimedia Sensor Networks（1）

       The 5th ENGII Conference——In recent years extensive research has opened challenging issues for wireless multimedia sensor networks (WMSNs) deployment. Among numerous challenges faced while designing architectures and protocols, maintaining connectivity and maximizing the network lifetime stand out as critical considerations. As a fundamental objective, maintaining is a dependable operation of a network. However, the resource constrained nature of sensor nodes and ad hoc network topology, often coupled with an unattended deployment, pose non-conventional challenges and motivate the need of special techniques for dependable design and management of wireless sensor networks. Data gathered from sensor nods in physical proximity tend to exhibit strong correlation.
