Routing
is the process of selecting the best path from source to destination. Nowadays
routing in three dimension in increasing since sensor nodes are deployed in the
three dimensional region. In this routing mechanism, the data packet in the
three dimensional region is routed using the geographic routing by constructing
a forwarding region. It is assumed that the nodes in network have the same
sensing range and same energy. The forwarding region is in the form of a
conical region is used to find the next forwarding node in the network towards
the sink node. Whenthe data packet is generated from a node
it constructs forwarding region to find the next node to forward the packet. Ifany node found then it forwards the packet to the node else
it twice the angle and search for the node. The searching process continues
until it reaches the maximum angle or it finds the node inside the region. When
no nodes found up to maximum angle then the corresponding node is considered as
the void node. If there is no lifetime
for the received packet then it can be discarded. For occurrence of the void
node the corresponding data packet can be traced back to the sender. So this
reduces the void node .problem.
