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. WSNs differ in many fundamental ways from MANETs. Among the differences that may impact the network and protocol design are (1) In most applications the WSNs need to work unattended, (2) Much of the processing in WSNs is data centric, (3) Many WSNs are mission-oriented and, therefore, may need to be programmed/re-programmed to achieve mission success, and (4) The need in WSNs for distributed calibration due to the nature of some monitoring applications. Early recognition of these and other differences between WSNs and other wireless networks including MANET has motivated the research community to develop solutions specifically designed for WSN. The tutorial will provide the participants with up-to-date survey or sensor networks and their various applications. In addition, we will provide pointers to the aspects of wireless sensor network research that may be relevant for a participant for a particular context.
