Performance analysis of end-to-end delay and reliability for linear wireless multimedia sensor networks

Wireless multimedia sensor networks (WMSNs) require data to be communicated timely and reliably. However, radio transmission errors incurred by wireless channel make it difficult to achieve these qualities simultaneously. To provide good quality of service (QoS) of WMSNs, parameters associated with the WMSNs need to be studied completely and best tradeoff needs to be made. To characterize the delay-reliability tradeoff, first, our goal is to evaluate the performance measures of the system, such as end-to-end delay and reliability in different situations and against different choices of system parameters (e.g., data rate, number of hops). Second, we characterize how the end-to-end delay and reliability affect the performance of the wireless multimedia sensor networks under indoor and outdoor environments. All scenarios are simulated with multiple runtimes by using NS-2 simulator and the results are evaluated and discussed.
