1.What is handoff? Handoff is the process of changing the channel associated with current connection while a call is in progress. Handoff is often initiated either by crossing a cell boundary or by deterioration in quality of signal in current channel. 2.Define multicasting. Multicasting is intended for group communication that supports the dissemination of information from a sender to all the receivers in a group. 3.Define a Wireless sensor network. Sensor networks are highly distributed networks of small, lightweight wireless nodes, deployed in large numbers to monitor the environment or system by the measurement of physical parameters such as temperature, pressure, or relative humidity. Each node of the sensor network consists of three subsystems: the sensor subsystem which senses the environment, the processing subsystem which performs local computations on the sensed data, and the communication subsystem which is responsible for message exchange with neighboring sensor nodes....
