Routing protocol
in sensor network: In
sensor network the routing of information can happen within a cluster or
between nodes of different clusters.
If the routing is happening
within a cluster. Then the protocol is called as intra cluster routing.
If the routing is happening
between the nodes of different clusters it is called as inter cluster routing.
Intracluster
routing
In intracluster routing, the
packets are transmitter with in a cluster It can be of two types.
1. Direct routing algorithm
2. Multihop routing algorithm
In direct routing, the cluster
head as the destination for all cluster nodes. The cluster nodes can
communicate directly with cluster nodes.
In multihop the destination is
reached through multiple hops. If there are many paths. Then only the path
which is energy efficient will be considered. In multihop routing, a node might
have to under go multiple hops before it reaches the destination. The sensor
node will be at different distances apart from other nodes. A packet from a
node is routed to a neighbor node that exhibits high energy. The number in the
node indicates the remaining energy in the node
