Different Characteristics

Even though a lot of research has made significant contributions to advances in sensor networks, sensor network protocols, which have different characteristics according to the target application, might confuse machine-to-machine (M2M) network designers when they choose the protocol most suitable for their specific applications. Therefore, this paper provides a well-defined taxonomy of low-power listening protocols by examining in detail the existing low-power sensor network protocols and evaluation results. It will also be very useful for helping M2M designers understand specific features of low-power media access control protocols as they design new M2M networks.

Real Time Identification

The advancement of information and communication technology directly influences the life style of human being by making their life easier, sophisticated in many circumstances. The healthcare sensor network is one of the emerging areas of research for both computer science and health professionals. The Quality of Service (QoS) requirement of the traffic in emergency situation is one of the key challenges in this network. The Medium Access Control (MAC) layer plays vital role for reliable and on time delivery in the healthcare sensor networks. The healthcare system provides remote monitoring, real-time identification and control information which helps in identifying the unusual patterns and making more precise information about the situation. In this chapter, we present the issues and challenges of supporting sensor networks for healthcare applications. Then we present an extensive survey of MAC protocols developed to address the major challenges and improve the capacity of healthcare system in WSN.

The Media

In wireless sensor networks, network security against virus propagation is one of the challenges with the applications. In severe cases, the network system may become paralyzed. In order to study the process of virus propagation in wireless sensor networks with the media access control mechanism, this paper uses the susceptible-infectious-removed (SIR) model to analyze the spreading process. It provides a theoretical basis for the development of virus immune mechanisms to solve network virus attack hidden dangers. The research shows that the media access control (MAC) mechanism in the wireless sensor network can inhibit the process of virus propagation, reduce the network virus propagating speed, and decrease the scale of infected nodes. The listen/sleep duty cycle of this mechanism will affect the suppression effect of virus propagation. The smaller the listen/sleep duty cycle, the stronger the suppression effect. Energy consumption has a peak value under specific infection probability. Meanwhile, it is also found that the spreading scale of the virus in wireless sensor networks can be effectively inhibited by the MAC mechanism.
