in wireless sensor network, the sensor nodes deploy round and near the sink , its form the bottleneck zone. How can calculate the radius of the circle , it will help to compute the zone?
What is parameter use to determine the bottleneck zone?
As I know you cannot find a precise radius of bottleneck. Regarding the random distribution of sensor nodes in environment at least in theory, it is somehow based on the locations of nodes. but you can consider a very close radius of base station proportion to environment size which is favorable to bottleneck.
Hi
bottleneck zone depends on the routing protocol you are using. For example. if all the nodes can communicate directly with the sink, there is no bottleneck zone since far nodes will die faster since they will use more power to transmit for longer distance. In clustering routing, bottleneck zone is distributed all over the network since cluster heads only transmit to the sink and they change randomly or by any algorithm. However, if you are speaking about a network where routing is implemented and far nodes can not directly reach the sink, the bottleneck zone will be the radius of the transmitted power of the nodes. if the power can reach only 10 m. the bottleneck will be 10 m since the nodes in this area must recieve and retransmit "route".
I hope this was what you are looking for
Find the last node in each direction that has so much data in its buffer that has to drop incoming packets.
