2. ABSTRACT
When n identical randomly located nodes, each capable of transmitting at W bits per second and
using a fixed range, form a wireless network, the throughput λ(n) obtainable by each node for a
randomly chosen destination is Θ(W/√(nlogn)) bits per second under a noninterference protocol.
If the nodes are optimally placed in a disk of unit area, traffic patterns are optimally assigned,
and each transmission's range is optimally chosen, the bit-distance product that can be
transported by the network per second is Θ(W√An) bit-meters per second. Thus even under
optimal circumstances, the throughput is only Θ(W/√n) bits per second for each node for a
destination nonvanishingly far away. Similar results also hold under an alternate physical model
where a required signal-to-interference ratio is specified for successful receptions.
Fundamentally, it is the need for every node all over the domain to share whatever portion of the
channel it is utilizing with nodes in its local neighborhood that is the reason for the constriction
in capacity. Splitting the channel into several subchannels does not change any of the results.
Some implications may be worth considering by designers. Since the throughput furnished to
each user diminishes to zero as the number of users is increased, perhaps networks connecting
smaller numbers of users, or featuring connections mostly with nearby neighbors, may be more
likely to be find acceptance.

3. ACKNOWLEDGEMENT
The seminar report on “WIRELESS ADHOC NETWORK” is outcome of guidance, moral
support and devotion bestowed on us throughout our work. For this we acknowledge and express
our profound sense of gratitude and thanks to everybody who have been a source of inspiration
during the project preparation.
It is with profound gratitude that we express our deep indebtedness to our Seminar Guide Mr.
Ashwani Kumar & Mr.Amit Ravi without whose support and guidance it would not have been
possible for this Seminar to have materialized and taken a concrete shape.
We offer our sincere phrases of thanks with innate humility to Ms. Pooja Verma H.O.D.
CSE/IT for providing their precious ideas, suggestions and help that enabled in shaping the
Seminar work.
Last but not the least we are indebted to our parents and friends for their constant encouragement
and helping us in our endeavor.
