sir,
is this sentence ok
An Improved Energy Efficient Routing Protocols for Stretch Attack in Wireless Ad hoc Sensor Networks

I'll have to accept that the sentence makes sense to those in the field. So:

An Improved Energy Efficient Routing Protocols...: which is it? one protocol - "an improved...protocol"; or two or more protocols:
Improved Energy Efficient Routing Protocols...

and capitalise "Ad Hoc"
