Abstract:
From recently, the innovative technology named as Constrained Application Protocol (CoAP) has been classified for numerous sensors in the field of IoT. Service discovery should be performed again in CoAP to support handover in mobile device. By this the handover delay and packets losses improved expressively. To reduce certain amount of packet losses and delay we will use a partial bicasting with buffering scheme. In proposed scheme, the bicasting is implemented in the “partial” region between the Mobile Access Gateway (MAG) and the Local Mobility Anchor (LMA) when a sensor node comes in the handover domain. At MAGnew data packets are buffered throughout handover to forward to sensors nodes and to decrease data losses.
