Mobile Ad Hoc and Sensor Networks
Prasant Mohapatra
University of California, Davis, USA

Audience: This tutorial is aimed both at researchers and practitioners. It will also immensely help students pursuing research in wireless networks. The discussions can be useful for both beginners and intermediate level audiences. The attendees will get an in-depth knowledge about the issues in mobile ad hoc and sensor networks. The prior knowledge required for this tutorial is a basic understanding of computers networks.

Course Description: Recent proliferation of wireless devices had considerably increased the need for networking and provisioning intercommunication between these devices for various applications. Broadly, the wireless networks can be classified into two categories. The cellular networks and wireless local area networks can be termed as infrastructure-based wireless networks. The second category, termed as infrastructureless wireless networks include mobile ad hoc networks and sensor networks. In this tutorial we will have an in-depth view of the issues related to MANETs and sensor networks. A broad classification of the wireless networks will be discussed first that will set the stage for the two major parts of the tutorial: MANETs and sensor networks. In the context of MANETs, we will describe the architecture, operations, and the challenges to meet the effectiveness of these networks. We will study the MAC layer protocols that have been proposed. In the context of network layer, we will discuss a variety of routing protocols proposed for both unicast and multicast communications. We will also examine various techniques for enhancing performance of routing in MANETs while considering the constraints of power, and other attributes. The performance of TCP and the enhancements proposed for TCP in MANET environments will be described. We will examine a layered view of QoS provisioning in MANETs, followed by an overview of the security issues including denial of service attacks and intrusion detection mechanisms. We will also have an in-depth look at the issues in sensor networks. After a discussion on the architecture and operations of sensor networks, we will analyze the deployment and localization issues in sensor networks. Since the sensor nodes have severe power constraints, we will discuss in detail about the energy conservation techniques in sensor networks. Several routing protocols proposed for sensor networks will be discussed in detail, followed by the description of the issues in the MAC layer. We will also discuss the cross-layer design issues in sensor networks. The tutorial will concluded with an overview of the future directions in MANETs as well as sensor networks.

Lecturer: Prasant Mohapatra received his Ph.D. in computer engineering from the Pennsylvania State University in 1993. He was an assistant professor and then an associate professor at Iowa State University from 1993 to 1999, and then at Michigan State University till 2001. Since then he has been at University of California, Davis, where he is a Professor in the Department of Computer Science. He has also worked in the Panasonic Information Networking and Technologies Laboratory (PINTL) and at the Technology Research Laboratory of Intel Corporation as Visiting Professor. Dr. Mohapatra has published extensively in various international journals and conferences. He has been an invited speaker at several universities and other organizations in several countries. His research work has been funded and collaborated by National Science Foundation, EMC Corporation, Panasonic Technologies, Hewlett Packard, Rockwell International, and Intel Corporation. Dr. Mohapatra is a senior member of the IEEE. He is currently on the editorial board of the IEEE Transactions on Computers. He was the Guest Editor for a Special Issue of IEEE Network that was published in January/February of 2003, the Program Vice-Chair of INFOCOM 2004. He has been on the program committees of several international conferences.
