AbstractDue to technological advances, it has become possible to design multifunctioning low power sensor nodes in small scale. These components perform sensing, data processing and communicating with each other and form Wireless sensor Networks (WSNs) incorporating together. WSNs consist of large numbers of sensor nodes (eg. by thousands) equipped with sensing, computing and communication abilities. Each node can sense the elements such as temperature, humidity, pressure of its environment, perform simple computations, and communicate with neighbors or base station. A greater number of sensors are needed for larger geographical regions with greater accuracy. Some application areas can be given as monitoring and detection for military purposes, target field imaging, intrusion detection, weather monitoring, security, surveillance, distributed computing, detecting ambient conditions such as temperature, movement, sound, light, or presence of certain objects.
One of the main goals of WSN routing is to prolong the lifetime of the network and prevent connectivity errors by employing aggressive energy management techniques. Power supplies of WSNs are limited and irreplaceable. However, the positions of the sensor nodes are usually not predetermined and deployed randomly in inaccessible geographic areas and disaster locations. This implies that the sensor nodes are expected to perform sensing and communication for long time with no maintenance or reorganization. Therefore, extensive collaboration between sensors nodes is required to perform high quality sensing and work with no fault. A traditional routing protocol can not be used for a sensor network. Thus, several studies in the literature are not suitable for WSN structures and it is needed to design network protocols considering criteria specific to WSN structures.
In this paper, effective routing methods will be developed and designed for WSN structures having many application areas such as military, medical, meteorology, and jeology. Thus, it will be provided that these systems will be more resistant to attacks and faults and have longer lifetime.
