Abstract— Swarm robotics is an advanced robotics field which involves co-operative behaviour implemented on robots. Swarm robots find its applications in a large number of fields like process automation, defence, surgery, surveillance etc.In the centralised swarm robotic approach, we have a master robot and one or more slave robots. For a known environment this approach has a very less response time. The master robot is basically in charge of the slaves and controls their actions through sending…

While ubiquitous Internet access is extremely convenient and enables marvelous new applications for mobile users, it also creates a major security vulnerability—by placing a passive receiver in the vicinity of the wireless transmitter, that receiver can obtain a copy of every packet that is transmitted! These packets can contain all kinds of sensitive information, including passwords, social security numbers, trade secrets, and private personal messages. A passive receiver that records a copy of…
