In conventional wireless sensor networks (WSNs), adding a few mobile nodes can greatly improve the control and sensing capabilities of the networks and can help researchers solve many challenges such as network deployment and scalability etc. The video capture, processing, and communication in wireless video sensor networks depend on the resources of the nodes forming the sensor networks. The major challenge in designing wireless sensor networks (WSNs) is the support of the functional, such as data latency, and the non-functional, such as data integrity etc. Careful sensor node placement can be a very effective optimization, means for achieving the desired design goals. In this paper we thoroughly survey and contrast the existing sensor node architectures. We also survey the research on optimized node placement in WSNs. We have provided the placement strategies into static and dynamic depending on whether the optimization is performed at the time of deployment or while the network is operational.
