Use MATLAB to provide solutions to the tasks listed below. 1) Network Modeling- Graph abstraction is important in modeling sensor networks. A graph is denoted by G = (N, E) where N is the set of nodes in the network and E is the set of links (communication links) among the nodes. Moreover, cost of maintaining the communication on a link between nodes and y (towards a certain objective, such as network lifetime maximization or end-to-end delay minimization) is denoted by c(x, y). a) First, construct a data structure for graph abstraction that will model a given network topology. b) Obtain the graph abstraction for the following network. It will be used for the following tasks. 6 6 12 W 4. V 3 5 u
