Performance Evaluation To evaluate the performance of synchronous energy efficient MAC protocols, we have carried out simulation studies in the networks of grid topologies as shown in.2 ]. For performance evaluation, we compare the energy efficiency of IEEE 802.11 DCF  with SMAC and TMAC. Performance Evaluation of WSNs Considering MAC and Routing Protocols Using Goodput and Delay Metrics Abstract: The Wireless Sensor Networks (WSNs) have a wide range of applications such as target detection and tracking, environmental monitoring, and tactical systems. In this paper, we study the effect of IEEE 802.15.4 MAC standard on the performance of AODV protocol for WSNs environment with mobile sensors.

Abstract Abstract—Receiver-based MAC (RB-MAC) is a preamble-sampling MAC protocol for WSNs in which a receiver node is dy-namically elected, among potential neighbors of the sender node, based on current channel conditions. In this paper, we evaluate the performance of RB-MAC and compare it with a sender-based preamble-sampling MAC protocol by using analytical methods, and implementation in real sensor nodes. We have used Configurable MAC (C-MAC), which is a framework to develop different MAC protocols in WSNs. This framework is realized as a component architecture that can produce application-specific communication protocols.
The experimental results presented in the paper corroborate with the analytical and numerical results showing how RB-MAC outperforms sender-based MAC protocols in terms of transmission delay, and energy consumption. Keywords-wireless sensor networks; MAC; configurability; en-ergy efficiency; delay.
Performance and traffic management for WSNs • 1. PERFORMANCE AND TRAFFIC MANAGEMENT Prepared by: Afrah Salman Supervised by: Assist. Mohammed Najim • Subjects • Introduction • Background • WSN Design Issues: MAC Protocols, Routing Protocols, Transport Protocols • Performance Modeling of WSNs: Performance Metrics, Basic Models, Network Models • Case Study: Simple Computation of the System Life Span • Practical Example • Introduction • WSNs are collections of compact-size, relatively inexpensive computational nodes that measure local environmental conditions or other parameters and forward such information to a central point for appropriate processing. • The performance of WNSs is affected strongly by other parameters in two groups: basic models and network models. • Basic models form the elementary blocks based on which the network models can be analyzed and the overall system performance studied. • Background ֍ WSNs usually consist of hundreds or thousands of sensor nodes scattered in a geographical area and one or multiple sink(s) for collecting information and transmitting it through wireless channels (Figure 11.1). ֍ The special design and characteristics of sensors and their applications make WSNs different from traditional networks.
