PPT-Medium Access Control Protocol for Wireless Sensor Network

Carleton University Presented by Mohamed Ajal majalconnectcarletonca Topics of Discussion Introduction Power consumption in WSNs Wireless MAC protocols Differences and Constraints. CMAC exploits concurrent wireless channel access based on empirical power control and physical interference models Nodes running CMAC estimate the level of interference based on the physical SignaltoInterferenceplus NoiseRatio SINR model and adjust Sublayer.

Congestion occurs when machines send too many packets to a network too quickly from the transport layer. . Performance will become degraded as packets are dropped and lost.. .. Wireless is Global. The standard radio frequencies run in the range of 3Hz to 300 GHz. There is other frequencies used for example the 222 MHz through 225 MHz is for amateur radio. If your interested in what frequencies your country is using for what? Take a look at the frequencies. Spring 2017. Wi-Fi. Wi-Fi:. name is NOT an abbreviation. play on “Hi-Fi” (high fidelity).
