This protocol uses local flooding technique for duty cycled devices using LLN with RPL, helps memory constrained devices to use multicast. Telecommunication is a communication of data or voice over a distance. Provided that the channel’s data capacity exceeds that required to support a single user, the channel may be shared through the use of multiplexing methods. Standards are developed either through the widespread use of a particular method or by a standard-setting organization. Different methods are used to deliver data from source to destination, for example in , the authors have proposed a lightweight forwarding algorithm to facilitate multicast in LLN for service discovery in smart objects. The right selection of data analysis method enables the researcher to meet the desired level of outcome and achieve the research objective efficiently (Bush et al, 2008).
