Mobile ad hoc Networks (MANETs) is a type of wireless ad hoc network which is a self-arranging network of mobile nodes connected by wireless links that create a discretionary topology. The mobile nodes are free to move randomly and to arrange themselves in a random manner. Thus, the wireless ad hoc network topology may expand rapidly and unpredictably. In(More)
—Video coding is controlled by coding algorithms and limited in a frame or group of frames within a sequence, without considering channel status condition. Besides the conventional coding algorithm, we need to develop methods to take care of resource allocation in cooperative wireless a sensor networks (CWSNs). The most challenging part of the CWSNs is the(More)
Selective encryption approaches for efficient multimedia content protection is proposed in wireless multimedia sensor networks (WMSNs) by many authors. Apart from these methodologies, the other important aspect which is discussed in some literatures is the combined optimization of multimedia quality, content protection and energy issues pertaining to(More)
Multimedia transmission in wireless multimedia sensor networks is often energy constraints. In practice the bit rate resulting from all the multimedia digitization formats are substantially larger than the bit rates of transmission channels that are available with the networks associated with these applications. For the purpose of efficient of storage and(More)

Scheduler is part of executing throughput in MAC Layer. A good scheduler provides high Quality of Service (QoS) and work towards getting more and more throughput. There are varieties of Scheduler based on different factors such as fairness and maximum feedback etc. Priority Scheduler is based on the need of the service to be catered. We have designed a(More)
Scheduler is part of MAC Layer that executes fair throughput. A good scheduler provides high Quality of Service (QoS) and work towards getting better throughput. There are varieties of Schedulers based on different factors such as fairness, maximum feedback, etc. Priority Scheduler is based on the need of the service to be catered. We have designed a(More)
MIMO applications that involve handheld devices such as cell phones pocket PCs or PDAs require antennas to be closely spaced, which result in mutual coupling among antennas and high spatial correlation for signals. In this paper, we investigate the use of dirty paper coding (DPC), an information theoretic analysis in order to compensate for the performance(More)
