Mobile computing introduces new flexibility such as continuous access to computing resources while the users travel.This facility raises new challenges such as fault tolerance in distributed mobile computing system. In this paper we present a non blocking token ring based checkpointing algorithm to tolerate the faults in the mobile computing environment. It is a single phase algorithm neither having the overhead of temporary checkpoints nor using dependency vector; and also it avoids the avalanche effect. Results shows that it outperforms two-phase algorithms.

In the recent years, researchers are focusing on the Vehicular Adhoc Network (VANET) field due to the lifesaving factor. VANET is one of the important application in the Mobile Adhoc Network (MANET).VANETs are defined as the set of the vehicles or the Road Side Unit(RSU) that communicate through the Wireless Local Area Network (WLAN) .VANET is an application of Intelligent Transportation System (ITS) that aims towards the safety and comfort of drivers and passengers . It is a network where vehicles communicate with each other to find the distance and finding the obstacles in the road. As it is a open network everyone can use it, so security and privacy is the major issue in the VANET. Especially in the authentication process, the vehicles needed to be authenticated before accessing or sending messages to the network. There are many attacks in the VANET application one of the major attack is the Sybil attack. Sybil attack is that attacker is creating multiple identities or making an illusion of the traffic congestion by the malicious nodes .This paper presents about the VANET overview, Sybil attack detection and proposes an approach neighborhood algorithm that is used to find the malicious nodes in Sybil attack.

GPRS is a relatively new technology that offers a packet based radio service with mobile network which is based on GSM circuit switching. To guarantee the QoS of voice service not being affected by the introduction of GPRS, preemptive priority is applied for voice calls to preempt GPRS data packet. Delivery of data packet from and to the mobile station within its service area. To provide packet mode transmission within the GSM network and interconnects with external packet data network. GPRS is used to wireless data communication. To improve your business performance and provide a successful business services. Limited cell capacity for all users. Lower access speed in reality. No support of GPRS Mobile Terminate Connection for a mobile server. The mobile computing is a wireless and wired data connection. Mobile computing invokes mobile hardware, mobile software and mobile communication. The communications are issues of adhoc network, protocol, infrastructure. The hardware are issues mobile devices and devices component. The software are requirements of mobile applications.
