This subject covers key applications and technological challenges in Mobile Ad Hoc and Wireless Sensor Networks: Routing Protocol Design and Security. Here students learn the design and security aspects of proactive and reactive routing protocols, such as DSDV, AODV, OLSR, DSR, SPIN, LEACH, TEEN and Directed Diffusion. Students will also learn how to use OPNET to evaluate the performance of AODV, OLSR and DSR.
