Clock Synchronization and LocalizationWSNs have numerous applications and are usually embedded in the environment. The basic objective in a WSN is to collect sensed data from a large number of SNs at one location commonly known as BS (or sink node), analyze the data to monitor the environment, and eventually control the actuator.

TCP, Neighborhood Formation, Reliable Transport, and Simulators for WSNsTCP is the widely used transport protocol and most of the IP-based technologies already well known and proven to be working. The pervasive nature of IP networks allows use of an existing infrastructure. But, TCP needs to distinguish between the natures of errors.

Sensor Node Coverage and Connectivity for Random DeploymentA comprehensive sensor node (SN) has been developed by the University of California at Berkeley and marketed by Crossbow, and the resulting product Mica mote (., [.]) is shown in Fig.?..

Broadcasting, Data Aggregation, and Opportunistic ForwardingA large number of SNs are randomly deployed in a WSN, and the question that comes is how each SN route data to BS? In order to conserve energy, usually multi-hop solution is adopted.

Coverage and Connectivity for Regular DeploymentsUp till now, we have considered WSN to have a large number of randomly deployed SNs, primarily useful for defense applications and natural disasters. But, they can be utilized using a regular topology pattern if the area is accessible and SNs can be placed at any point within the area.

Routing and Performance of Regular WSNsWe considered the usefulness of regular deployments of WSNs, and it is time now to quantify some of the specific parameters and compare how they perform as compared to a random scheme. An obvious reason to use regular scheme is that a desired area can be covered by fewer SNs and some underlying characteristics are shown in Table?15.1.
