In the past few years wireless sensor networks have received a greater interest in application such as disaster management, border protection, combat field reconnaissance and security surveillance. Sensor nodes are expected to operate autonomously in unattended environments and potentially in large numbers. Failures are inevitable in wireless sensor(More)
Many routing protocols in mobile ad-hoc networks have been developed by many researchers. One of ad-hoc routing protocol types is the on-demand routing that establishes a route to a destination node only when required. However, most of on-demand routing protocols reestablish a new route after a route break. In this paper, we propose a new route maintenance(More)
Some WSN by a lot of immobile node and with the limited energy and without further charge of energy. Whereas extension of many sensor nodes and their operation. Hence it is normal.unactive nodes miss their communication in network, hence split the network. For avoidance split of network, we proposed a fault recovery corrupted node and Self Healing is(More)

The majority of localization algorithms start at a known position and add internal movement data and external environment data to this position each cycle. If the robot isreplaced or the sensor data quality is too low, these algorithms are usually not able to recover to a useful position estimation Members of these so-called local approaches are the linear(More)
In this paper, a new page replacement algorithm has been represented that has a better performance in average than quondam methods. A major attempt in such an algorithm is to substitute characteristics of some quondam methods engrossed by a new idea. The key concept of proposed scheme is to decrease overall page fault rate for system i. e. to increase the(More)
Sensor network has occupied an important space in current research. Small size of the sensor nodes put constraint on the hardware capabilities and battery supported on it. In this paper we have discussed threshold policy for selecting a particular state of sensor node with fixed threshold policy. Threshold policies are needed whenever to choose the better(More)
