Dear sir, i am doing my project in wireless adhoc networks using ns2..i hav some basic doubts regarding adhoc scenario in aodv..
(1) In any wireless adhoc scenario, the neighboring nodes are decided based on transmission range right...then, i face a problem stated below.. consider 4 nodes (n1,n2,n3,n4) in the same transmission range..n2 being near to n1,n3 being near to n2 and n4 being near to n3.. now, if i send a packet from n1 to n4, it is going via n1-n2-n3-n4...not directly from n1 to n4(which is the expected action because n1 and n4 are in same transmission range).. I dont know why is it happening like this? can u please give a soln to my problem.. Note: i used AODV protocol (2) I hav connected an instance of my agent to each of my nodes..should i connect the two agents of each pair of nodes in wireless ad! hoc topograpy to enable packet transmission between them? (3) In wireless adhoc network, Can each node promiscuously listen to the transmission of its neighboring node (i.e. a node in its transmission range) by default or should i set some flag for setting a node in promiscuous mode? I wl be very much thankful to u if u clear me the above doubts in wireless adhoc scenario... regards, krithiga
