Graduate-level research in human-computer interaction, artificial intelligence, programming, databases, and software engineering, among other areas, makes this one of the most prominent departments nationally. A key area of strength is the collaboration opportunities with other centers and departments. In one example of that collaboration, the department will share in a $250 million gift to the university from the Coleman Institute to develop technologies that will enhance the lives of people with cognitive disabilities. Over the next few years the department will also use four successive awards to improve its computing infrastructure.
WSN nodes resource constrained. In order to keep the size and the cost of the nodes down, the nodes have limited processing power, memory and radio range. However, the resource constraint which has the most significant impact on many WSNs is the constraint on energy. WSN nodes are battery operated. Many wireless sensor networks are deployed in locations where battery replacement is not feasible. A node has to be discarded when the battery depletes. Energy scavenging may alleviate this problem in some sensor networks. Most WSN protocols are very conscious of the limited supply of energy, and try to conserve energy.
