CICV: Cross Indexing and Cross Verification Algorithm Based Service Discovery in Pervasive Computing

One of the drastically growing industries is pervasive computing where it integrates human, smart devices, cloud and internet. Number of devices and number of people using services in pervasive computing is increasing day-by-day. Due to dynamic changes in scalability it is very difficult to select and provide an accurate service to the user request. In this paper, Cross-Indexing and Cross-Verification (CICV) algorithm is used to investigate and provide an accurate, relevant service to the appropriate user requests in time. CICV creates and maintains the information about the devices and services with location information including other Meta information for selecting and providing services to the user requests. Also CICV provides services in three different ways as unicast, broad cast and multi cast according to the requests similarity, which reduces the time and computational complexity. The simulation is implemented in NS2 software and the results are compared with the existing approach results in order to evaluate the performance of the proposed approach.
