Performance Evaluation of Target Trajectory and Angular Position Discovery Methods in Wireless Sensor Networks

In sensor networks Target Tracking defines how accurate a targets position can be measured. We consider both stationary target and mobile target. Since the mobile target is unknown, the mobile sensor controller utilizes the measurement collected by a wireless sensor network in terms of the mobile target signal2019;s time of arrival (TOA).We proposed time of arrival2 (TOA2) algorithms which consider time to live (TTL). We investigate the correlations and sensitivity from a set of system parameters. We derive the minimum number of mobile sensors that are required to maintain the resolution for target tracking in a mobile sensor network (MSN).The simulation results demonstrate the tracking performance can be improved by an order of magnitude with the same number of sensors when compared with that of the static sensor environment

A REVIEW AND RESEARCH TOWARDS SECURITY IN MOBILE CLOUD COMPUTING

Mobile cloud computing is a combination of cloud computing and mobiles. Mobile cloud computing represents an infrastructure where data processing and storage of the data happens away from the mobile device   because of the  limited resources which is provided by the mobile infrastructure. Total of 42.8 million (1.1% of total mobile users) people are Mobile Cloud Computing users in 2008 which will be about 998 million (19% of total mobile users) by 2015. This is because of the reason of security and cost. Most of the IT  Executives and  CEOs are not willing to adopt the MCC infrastructure because of the security concern. Inspite of many efforts and research which has been made there are many loopholes  and challenges which are still present. In this paper we present the security aspects and possible solutions for the same

EFFICIENT PACKET DELIVERY FRAMEWORK USING GEO-CAST ROUTING APPROACH FOR A VEHICULAR AD-HOC NETWORK (VANET)

In recent years, the technology of Vehicular Ad-hoc Networks(VANET's) communication has become more popular, allowing people to share road information with each other and use it while driving.Vehicular Ad-hoc Networks are special type of Mobile Ad-hoc Networks (MANET's) in which nodes are highly motile, so the network topology changes very fast. In order to form the communication there are several routing protocols provide to optimal path for delivery of packets. In this paper, the Geo-cast routing(GPRs) are applied for both urban and highway areas based on traffic environment. The two protocols Coverage Aware Geo-cast Routing(CAGR) in urban vehicular networks and Information Propagation Speed Analysis(IPSA)in highway vehicular networks are discussed.The path formation from source vehicle to destination vehicle based on different criteria are considered. The results  are analyzed using MATLAB
