Simulation of a WiMAX network to evaluate the performance of MAC IEEE 802.16 during the IR phase of Network Entry and Initialization
Pervasive computing is also called as ubiquitous computing, which means \"Being present everywhere at once\" or \"Constantly encountered\". The main idea behind making these pervasive computing systems is that these systems improve living by performing computations on their own, without having to be monitored by anyone. These systems are targeted to become invisible to the user i.e., they perform their tasks without the user's knowledge. To achieve this environment, the underlying requirement is a network. One of the biggest constraints in achieving this environment is the \"Last mile\" problem.
