I am doing a project using RF communication between pic microcontrollers. I would lik开发者_如何转开发e to implement a protocol for better performance. How to implement the protocol in the RF module?

That's a lot of work from scratch. Start by reading about the OSI 7 layer protocol model and then how other protocols work. Or choose an existing protocol such as Microchip's MiWi. You'll find that the RF chip you are using may help with some aspects of the protocol. Don't forget to read up on the regulatory requirements for your geographic area (ETSI in Europe, FCC in US etc). They can dicate more than just transmit power and frequency, they can include message timings and duty cycle which will impact your software and protocol design.
