Abstract

In this paper a new method of microscopic feature extraction on image processing has been proposed. The proposed technique is effective in extracting desired microscopic features from an image. In this technique dynamic threshold technique is applied on the image in order to remove the background, then vector median filter is applied to remove the noisy pixels for achieving clear image, and finally by digital morphological algorithm to find the desired location in an image is obtained.

Abstract

In this paper a wormhole detection technique has been proposed which makes use of AODV as an on demand routing protocol and secure neighbour detection protocol with certain modifications. In the technique, sender floods the route request packets in search of destination and in return the receiver responds by sending the route reply. The route reply contains the number of routes that lead to it, sending and receiving time, the identification of intermediate nodes and the request that the sender had sent. During analyzing the reply, sender confirms the number of routes by sending packets of verification to individual nodes whose identification has been stated by the receiver and based upon the delay in time i.e., Δt, wormhole link is detected. Analysis proves that the proposed technique not only detects the wormhole link but also provides a verification mechanism to judge the validity of nodes.

Abstract

Wireless mesh network (WMN) is a wireless networking model which currently attracts research and industry. In WMN every node passes information to the nearest node and there may be number of hops from one node to the other. In WMN the information is forward using the best possible route to any destination. The best path can be determined using the routing protocol. The congestion problem arises when every time routing protocol determines the same best path due to which traffic load occurs on that path while other path seldom used. Due to the abrupt use of single path the packets may drop causes the greater effect on the network’s performance. In this paper a technique is used to overcome such congestion problem that faced by the network. In the technique priority based selection mechanism for the paths is adopted which can ensure the performance of the network.
