MAC Protocol for Wireless Multimedia Sensor Network: A Survey
نویسندگان
چکیده
Wireless Multimedia Sensor Networks (WMSNs) are wireless connected sensor’s with audio and video capabilities in addition to scalar sensing. Limited availability of bandwidth is a major constraint for multimedia data in WMSNs. The requirement of real time streaming poses another challenge in the network. Medium access control (MAC) protocols designed for traditional wireless sensor networks cannot be adopted for WMSNs. The overhead caused by multimedia data results in congestion and data losses. In this paper various MAC protocols for WMSNs are surveyed and open research issues are discussed in detail. Architecture of WMSNs is also explored along with different heterogeneous type of setups.
