Major application of
sensor network is to collect information from environment.
When users monitor events or analyze sensed data, data query becomes an important operation in wireless
sensor networks. Recently, many existing privacy techniques can be employed in
sensor network scenarios.
Wireless
sensor network technologies can make up for these deficiencies.
The Next Generation Air Pollution Monitoring System (TNGAPMS) classified into three types of
sensor networks based upon the carriers of the sensing elements are Sensors static
Sensor Network (SSN), Community
Sensor Network (CSN), Vehicle
Sensor Networks (VSN).
* Barrier coverage: minimizing the probability of undetected intruders through the barrier or
sensor network.
In this paper we are trying to explore various aspects of medium access control (MAC) protocols in wireless
sensor network. Creating a
sensor network infrastructure, establishing communication links for data transfer between them and efficiently share communication resources between each sensor nodes are the important objectives of MAC protocol.
Nowadays, there are a large variety of networks spanning from the well-known cellular networks to non-infrastructure wireless networks such as mobile ad hoc networks and
sensor networks. Communication security is essential to the success of wireless
sensor network applications, especially for those mission-critical applications working in unattended and even hostile environments.
With the widespread application of wireless
sensor network technology, there are more and more usage and researches of wireless sensor technology, such as in the fields of environmental testing, geological exploration and even military information transmission, in which wireless
sensor network technology is dominant (Gong, 2011).
Internet of Things enabler Telit has introduced a new integration agreement with Libelium, a maker of wireless
sensor network hardware, the company said.
