PEGASIS - This is a greedy technique to find the group of nodes whose data packets have to be aggregated. The network lifetime of this protocol is twice that of LEACH protocol.
TEEN & APTEEN - Cluster head broadcasts thresholds along with different attributes to its group to decide when to switch the cluster nodes' transmitter. This functionality helps to save energy in the network.
MECN - This is another clustering technique, where sub-networks are formed in the network based on the transmission power of the nodes. The sub-network used for transmission is the one which will consume less transmission power.
VGA - The entire network is divided into grids and each grid forms a separate cluster. The routing mechanism aggregates locally and globally at each cluster head in the grid and at the designated master aggregator respectively.
HPAR - The Max-min zPmin algorithm will ensure routing of the data packets along the route which has maximum over all minimum of the remaining power of the nodes.
I think I threw this question during the presentation, but since I forgot the answer, here it is again: Which of this protocols is for mobile networks? Are all of them for wireless sensors with static nodes?
ReplyDeleteYes. These are developed for wireless sensor networks with static nodes.
ReplyDeleteI would think that generally routing protocols for a wireless sensor network are designed for static nodes. At least more protocols are designed for static nodes over mobile nodes.
