3. Consider a relav transmission as shown in Figure D3. Mode A transmits one pack E in a time slot fashion. Node B then transmits the received packet to node B. No node C can be in one of two modes, i.e., active and sleep modes. Node B can re packet from node A if node B is in an active mode. Likewise. node B can tra packet to node C only when both node El and node C are in the active mode. No node C are in the active mode with probabilities Pa and Po, respectivelv. Althoug has received a packet from node A, node B can switch to The sleep mode protialailitylr 'lF'g. Assume that there is no transmission error. and node A is alwa active mode. Derive the prohahilitvr that node C will receive a packet from node time slots. W Figure {313
