POWER AWARE ROUTING PROTOCOL(5)

PROTOCOL(5)

Route Discovery

In DSR, activity begins with the source node flooding the network with RREQ packets when it has data to send. An intermediate node broadcasts the RREQ unless:

• It gets a path to the destination from its cache
• It has previously broadcast the same RREQ packet. (This fact is known from the sequence number of the RREQ and the sender ID.)

Consequently, intermediate nodes forward only the first received RREQ packet. The destination node only replies to the first arrivedRREQ since that packet tends to take the shortest path.

In PAR, all nodes except the destination calculate their link cost, Cjand add it to the path cost in the header of the RREQ packet. When an intermediate node receives a RREQ packet, it starts a timer (Tr) and keeps the cost in the header of that packet as Min-Cost. If additional RREQs arrive with same destination and sequence number, the cost of the newly arrived RREQ packet is compared to the Min-Cost. If the new packet has a lower cost, Min-Cost is changed to this new value and the new RREQ packet is forwarded. Otherwise, the new RREQ packet is dropped.

Representative APR 391%

Let's say you want to borrow $100 for two week. Lender can charge you $15 for borrowing $100 for two weeks. You will need to return $115 to the lender at the end of 2 weeks. The cost of the $100 loan is a $15 finance charge and an annual percentage rate of 391 percent. If you decide to roll over the loan for another two weeks, lender can charge you another $15. If you roll-over the loan three times, the finance charge would climb to $60 to borrow the $100.

Implications of Non-payment: Some lenders in our network may automatically roll over your existing loan for another two weeks if you don't pay back the loan on time. Fees for renewing the loan range from lender to lender. Most of the time these fees equal the fees you paid to get the initial payday loan. We ask lenders in our network to follow legal and ethical collection practices set by industry associations and government agencies. Non-payment of a payday loan might negatively effect your credit history.
