Wireless sensor sensor networks lead to faults and errors by sensitivity of the sensor nodes. For solving this problem, first i have discuss the faults or the types of failure in network, describe the approaches of fault management . Various effective algorithms or adaptive fault tolerant mechanisms are designed till now to achieve a good fault management. In this paper we will discuss already implemented fault management approaches and Limitations of these approaches and try to recover the faults by the concept of mobile agents.

A wireless sensor network is a collection of many sensor nodes which has a capability of wireless communication and sensing the network.Wireless sensor network has lot of nodes which has capability to convert the sensed characteristics such as temperature,pressure into a form recognize by user.These sensor nodes have limited processing power, finite energy supply.wireless sensor networks are deployed in the remote areas ,like environmental sensing such as oceans, glaciers,volcanoes etc. Where they can’t operate properly.Hence different types of faults occur in the network.
Fault management is important tool in the networking field that minimizes the network failure and optimize the performance of the network.
Functions of fault management:-
 Regular monitoring of system status
 Diagnostics
 Tracing the location of actual failure
 Recovered the issues creating by failure


There are three different types of Faults in the network
A. Permanent Faults:- Hardware fault of a sensor node is permanent fault. It exists until the repair action has taken place.
B. Intermittent Faults:- It is due to the unstable consequences of hardware and software characteristics. This implies maximum degradati...

...o accomplish it is polling network elements by request messages and fetched data is processed at the manager node. This involves huge amount of data to be travelled over network links. Processing capability of centralized node must also be strong enough to sustain such enormous fault data.The centralized approach has been considered as the common solution ,Which enables the base station with unlimited resources to execute a wide range of recovery functions in the network. but the limited hardware and software capability of a node also places restriction on the design of management functions.

Another problems concerns encryption and authentication in our agent infrastructure and some alternate recovery action can also be proposed for all the problems discovered. so it can be topic of future research to propose some other recovery actions for better processing.

Load Balanced Routing with Constant Stretch for Wireless Sensor Network with Holes

- Because of its simplicity and scalability, geographic routing is a popular approach in wireless sensor networks, which can achieve a near-optimal routing path in the networks without of holes. With the occurrence of holes, however, geographic routing faces the problems of hole diffusion and routing path enlargement. Several recent proposals attempt to fix these issues by deploying a special, forbidding area around the hole, which helps to improve the congestion on the hole boundary but still causes significant load unbalancing due to static detour routes bypassing this fixed forbidding area....   [tags: wireless sensor networks]

Wireless Sensor Network: Link Quality Based Hierarchical Routing Algorithm for 6LoWPAN

- ... One interesting example application of 6LoWPAN is in facility management, which is the management of large facilities using a combination of building automation, asset management and other embedded systems. The devices in the 6LoWPAN network need to have a appropriate routing mechanism in order to be able to route keeping in mind the constraints in the devices such as memory and power. The protocols should try to minimize the energy usage and improve the lifetime of the entire network. When the concept of link quality is combined with the routing protocols the lifetime of the network is always greatly enhanced....   [tags: IP-based application, internet of things]
