Highly popular websires can suffer classicrrl congestion collapse because of the abilip of nurgoing 'bursty' data ro congest the server side link. Using the well known and recognized nenvork simulator ns we look ar rhe effect that this congestion collapse has on user perceived performonce (UPP) of a simulated websire.We developed a prorocol overlay for HTTP/I.I and a complementary distribution infrastructure ro nlleviure the eflecrs of this congestion. Our Protocol Hi'TP[PZP), shows promise for increasing the maximum load of websites during rimes of high and wety high websire loadand link contention.In our simulated environment, xTTP(P2P) significantly decreases rhe rime required for users to download the web page they requesr. The prorocol also disrributes rhe redirected trafJic over the network to reduce secondary transient network congestion.

A unique and efficient system model is proposed for sensor networks to create sensor-smart highways. The approach first considers various cell geometries encountered with 2-D roads and then extends the same to 3-D roads. Mathematical relations describing each type of cell are derived, and the analyses indicate the numbers and positions of sensor nodes needed in each cell of a certain type. We then propose algorithms for computing the deployment positions of sensor nodes on roads by describing them as consisting of cells of different geometries. We also validate the approach by computing a sensor deployment using real geospatial data.
