Suggestions/Improvements/Future Work: If a buffer is full there would be a lot of dropped packets decreasing the throughput. A method to overcome this drawback is that we could have the node with its buffer 75% full broadcast a special packet Buffer Full Packet MAC Virtual Clustering technique needs to be further investigated An adaptive election algorithm can be incorporated where the schedule and neighborhood information is used to select the transmitter and receivers for the current time slot, hence avoiding collision and increasing energy conservation References
