1. Joint Cooperative Routing and Power Allocation for
Collision Minimization in Wireless Sensor Networks With
Multiple Flows
ABSTRACT:
In this letter, a cross-layer cooperative routing algorithm is proposed for
minimizing the collision probability subject to an end-to-end outage probability
constraint. We develop a collision minimization algorithm by combining
cooperative transmission, optimal power allocation, and route selection. The
proposed cooperative routing algorithm, called minimum collision cooperative
routing (MCCR), selects the route that causes minimum collision probability to
other nodes in the network. Results show that MCCR can significantly reduce the
collision probability compared with existing cooperative routing schemes.
EXISTING SYSTEM:
Existing cooperative routing algorithms in the literature can be divided into two
categories: (1) routing algorithms which are implemented by first selecting the
optimal route based on direct transmission in each link and then using cooperative
transmission over the links of the selected route and (2) routing algorithms which
take into account the availability of the cooperative transmission on each link
during route selection. Routing schemes in the second category are more complex

2. but more efficient. One of the heuristic cooperative routing algorithms is called the
Cooperative Along Non-cooperative (CAN-L) shortest path algorithm with the
objective of minimizing total transmitted power. The Minimum Power Cooperative
Routing (MPCR) algorithm makes routing decisions by assuming the cooperative
transmission is also available for each link. MPCR finds the route that minimizes
the total transmission power.
DISADVANTAGES OF EXISTING SYSTEM:
 Existing algorithms are more complex
 MPCR algorithm considered on only transmission power
PROPOSED SYSTEM:
In this project, we propose cooperative routing algorithm, called minimum
collision cooperative routing (MCCR). In this project, we aim to design a cross-
layer cooperative routing scheme for minimizing the collision probability subject
to an end-to-end outage probability constraint. The cross-layer scheme is designed
by combining cooperative transmission, power allocation, and route selection when
there are multiple flows in the network.

 Reduce the transmission power
 It provides minimum collision probability
