Title Future of Connectivity: Mobile Ad Hoc Network Enabled Software Defined Radio

Software Defined Radio (SDR) is the technology that provides a high level of cognition to communication and connectivity to a broad spectrum of applications. High-end applications require a very flexible platform consisting of a number of programmable processors like Digital Signal Processors (DSPs), Field Programmable Gate Arrays (FPGAs) and General Purpose Micro-Controllers. These systems still have few Application Specific Integrated Circuits (ASICs) for SDR specific functionality. The requisite flexibility and high-data rate require SDR to have super computing power in a small form factor. The SDR in Mobile Ad Hoc Network configuration would also require each radio to have networking functionality. As there are no base station or infrastructure for forming a network and each SDR should also exhibit the same behavior, this require an SDR to have the relevant functionality of a base station and mobile switching center (MSC) for mobile networking.  Further to this the network should also be able to self-healing and self-forming along with over the air management & up-gradations. The cognition also enable them to provide high-data rate in multiple network forming capabilities for multimedia applications. Each layer of TCP/IP protocols in mobile ad hoc network setting invites innovative solution for effective operation. Examples are a number of networking protocols, Medium Access Control (MAC) and Link Layer protocol specific to SDR based mobile ad hoc network for simultaneous voice and data applications. Many application would also require guaranteed security. This needs red-black separation ensuring no access to un-encrypted data from an open interface or from the air. The security and networking also requires Network management and key management solution.  The intended talk on SDR would address all the areas for students and practitioners to consider it for research and development. I envisioned a time will come when SDR would take over a significant commercial mobile space for ease and economical operation
