No doubt, saswatabanerjee has given a most sincere answer to your query. However, there are a few things that you must consider as well.
Golden rules for negotiating a job offer
Create a mutual understanding with the recruiter on why you deserve what you're asking for. The increment isn't something recruiters will present to you in a chocolate box; you'll have to explain why you think you deserve it. Proposals are not always considered based on the job profile or candidate's skills, but they are often created within the company budget.
Therefore, you'll have to be reasonable about why you deserve what you're asking for and keep everything as clear as a sunny sky. If you think they're not considering your suggestions, you must opt for other options.
It would be easier for you if you negotiate on multiple issues simultaneously, not serially. And remember, they're not out to get you.
