The advancements of Information Technology have led to many developments that make life easier and faster with high reachability and efficiency. There is a drastic improvement in the area of distributed applications with the advent of mobile agent technology over the usual client/server framework. Applying mobile agent technology in the area of distributed applications improves the performance and quality of service. Mobile agent technologies in particular have taken a prominent place in handling effective road and vehicle traffic (VANET). This paper highlights on the integration of previously defined MATLB, PCM and MSA Agent and proposes an approach for reducing the size of the mobile agent that helps in data collection of vehicles in the VANET for effective and efficient traffic control. This paper is an advancement of agent load shedding algorithm and an attempt to optimize the size reduction process. This reduction in size of mobile agents will enhance the performance of VANET making the agents more acceptable by the hosts and correspondingly building an effective co-operative vehicular network.

The software productivity and quality can be improved by the systematic reuse of software. Reuse and reusability are the two important factors in the software development. Reusability is a prime principle in service oriented architecture. For realizing the reuse of service, the adequacy of ability of service reuse should be properly quantified. The quantification of reuse needs a suite of metrics and many metrics are also available. Each research and publication focuses on different qualities of service to propose a set of metrics for service reusability. This paper studies the service reusability to understand the concept and survey the reusability metrics. The purpose of the paper is exploring the available service reusability metrics for further research.
