Many Wireless Sensor Network (WSN) applications necessitate secure multicast services for the purpose of broadcasting delay sensitive data like video files and live telecast at fixed timeslot. This paper provides a novel method to deal with end-to-end delay and drop rate of packets. Opportunistic Routing chooses a link based on the maximum probability of packet delivery ratio. Null key generation helps in authenticating packets to the receiver. Markov decision process based adaptive scheduling algorithm determines the time slot for packet transmission.
