Handover System in Mobile Communication System
Abstract: Handover is the process of providing continuous communication when the mobile node (MN) moves from one cell region to another cell region. Handoff or handover transferred the data from one channel to another channel. Both hard handover and soft handover are to transfer the control from source cell to destination cell in Code Division Multiple Access (CDMA) and Non-CDMA network.Keywords: Handover, hand off, soft handover, hard handover, CDMA, cell, base …

A Review on Sinkhole Attack in Ad hoc Network
Abstract: Security is key aspect in wireless network. The security implementation in wired network is easy as compared to wireless mobile network due to its centralized architecture and control. MANET is developing examination area with real-world applications. This new group of networks is dissimilar from the wired one in many aspects like network substructure, resources and direction-finding protocols, routing strategies, etc. However, MANET is mainly vulnerable owed to its central characteristics, …

Boundry Based Detection and Prevantion of Sink Hole Attacks in MANET
Abstract: Wireless Sensor network is comprised of huge amount of small cost minimal power sensor nodes. The flexibility of wireless sensor networks makes them very attractive to attackers. Wireless sensor networks face resource constraints containing limits on the memory capacity, communication, power and computational power. Also, since they are frequently organized in unfriendly atmospheres and left unattended, they are vulnerable to numerous attacks. One of the major well known and severe …

Black Hole and Gray Hole Detection and Prevention by Using Table Driven Knowledge Based Approach
Abstract: MANET is gain popularity now a days, its vulnerable for attack black hole attack is one of the security threat in MANET in which attacker node attract the traffic and then drop all the packets gray hole attack some time behave like malicious node to determine this behavior is very tough. In this paper we use table driven knowledge based approach on behavior of node and store the path information …
